FROM THE PUBLICATIONS CHAIRMAN

This issue of the Proceedings brings you

the most up to date information about the 2016 Banquet and Awards Ceremony and

the Technical Symposium. We are returning to the New York City Athletic Club to recognize our 2016 RCA Award recipients and to share the evening with our first-ever Nobel Laureate! Dr. Joe Taylor received the Nobel Prize in Physics in 1993 for discovering the Hulse-Taylor binary pulsar system, and he is this year’s keynote speaker. We encourage all of you to join your fellow RCA members at an outstanding event and to welcome Joe.

The Fall 2016 issue of the Proceedings focuses on our award

recipients and our new RCA Fellows. Biographical information for both groups of individuals is included. Complete information about programs and biographies for the speakers at the Technical Symposium is also presented.

We have a wide range of contributors and articles. Thanks to Chip Cohen, we have conducted an interview with a colleague of Dr. Joe Taylor, Dr. Joel Weisberg, who discusses Joe’s discovery, what it was like to work with him, and the impact of the discovery. We also visit some earlier history, touching on the origins of pagers with Mike Clarson and reexamining the Radio Corporation of America’s first portable radios. The Voices of Tomorrow returns with contributions from two young authors, Divyam Mishra and Austin Shaller, who

describe home sensor networks and digital transceivers, respectively. Both of these authors were "discovered" by Carole Perry, who has included the latest report of her Youth Forum activities.

Congratulations to all of RCA’s members for their continuing successes. We invite each of you to contribute articles, news stories and ideas for future content. We also welcome your comments, recommendations, and suggestions on ways to further improve the Proceedings.

RCA 2016 BANQUET TO FEATURE NOBEL LAUREATE JOE TAYLOR, K1JT

RCA is thrilled to announce that Joseph Hooton Taylor, Jr. will be featured at the 2016 Banquet and awards ceremony. This is

the first time that RCA will be welcoming a Nobel Laureate, and our members will not want to miss this incredible opportunity.

“Joe,” a Princeton University Professor, is a lifetime amateur radio operator. He and Russell Hulse received the Nobel Prize in Physics in 1993 for their discovery in 1975 of the first binary pulsar system. Professor Taylor will speak about topics of interest to RCA, including comments about the recent historic discovery of gravitational waves announced February 11, 2016. This announcement, made by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the VIRGO Collaboration, confirmed Albert Einstein’s theories about the existence of gravitational waves 100 years after they were first published.

A pulsar, or pulsating radio star, is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth similar to the way a lighthouse can be seen only when the light is pointed in the direction of an observer. This behavior is responsible for the pulsed appearance of the emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed to be one of the candidates of high and ultra-high energy astroparticles.

In 1974, Taylor and Hulse discovered for the first time a pulsar in a binary system. This pulsar orbited another neutron star with an orbital period of just eight hours. Einstein’s theory of general

relativity predicts that this system should emit strong gravitational radiation, causing the orbit to continually contract as it loses orbital energy. Observations of the pulsar soon confirmed this prediction, providing the first-ever evidence of the existence of gravitational waves. In 1993, Taylor and Hulse received the Nobel Prize in Physics for their discovery.

Joe was born in 1941 in Philadelphia, but grew up in Cinnaminson Township, New Jersey. He became an amateur radio operator as a teenager in the 1950s. Today, he continues to be an active ham and is likely to be on the air participating in several contests each year. In 2001, he authored the weak signal processing suite WSJT that is widely used for Earth-Moon-Earth and meteor scatter communication modes.

Joe received a B.A. in physics at Haverford College in 1963, and a Ph.D. in astronomy at Harvard University in 1968. He went to the University of Massachusetts at Amherst, eventually becoming Professor of Astronomy and Associate Director of the Five College Radio Astronomy Observatory. His thesis work was on lunar occultation measurements. In November 1967, the first pulsar observation was made by Jocelyn Bell Burnell and Antony Hewish, about the time Joe completed his Ph.D. Joe then began studying pulsars after finishing his graduate studies at Harvard. He immediately went to the National Radio Astronomy Observatory’s telescopes in Green Bank, West Virginia. Since then, he has worked on all aspects of pulsar astrophysics. In 1975, Joe and Hulse made their own discovery during a survey of pulsars made at the Arecibo Observatory in Puerto Rico. In 1980, he moved to Princeton University, where he was the James S. McDonnell Distinguished University Professor in

Physics, having also served for six years as Dean of Faculty. He retired from Princeton in 2006.

Joe has continued to be an expert on the measurement of binary pulsar properties because these phenomena provide a stringent test of Einstein’s general theory of relativity, and of the existence of gravitational waves. Binary star systems lose energy and slow down because they radiate their energy. The rate of energy loss can be computed using various theories of general relativity.

Joe Taylor first obtained his amateur radio license as a teenager, which led him to the field of radio astronomy. He is well known in the field of amateur radio weak signal communication and currently has the call sign K1JT (previously K2ITP, WA1LXQ, W1HFV, and VK2BJX). He mounted an expedition in April 2010 to use the Arecibo Radio Telescope to conduct moon bounce with amateur radio operators around the world using voice, Morse code, and digital communications. He wrote several computer programs and communications protocols, including WSJT (“Weak Signal/Joe Taylor”), a software package and protocol suite that utilizes computer-generated messages in conjunction with radio transceivers to communicate over long distances with other amateur radio operators. WSJT is useful for passing short messages via non-traditional radio communications methods, such as moon bounce and meteor scatter, and other low signal-to-noise ratio paths. It is also useful for extremely long-distance contacts using very-low power transmissions.

Joe was among the first group of MacArthur Fellows. He has served on many boards, committees, and panels, co-chairing the Decadal Panel that produced the report Astronomy and Astrophysics in the New Millennium that established the United States’ national priorities in astronomy and astrophysics for the period 2000-2010. He was a guest of honor in the 2009 International Physics Olympiad. His many awards include:

• Heineman Prize of the American Astronomical Society (1980) (inaugural)

• Fellow of the American Academy of Arts and Sciences (1982)

• Henry Draper Medal of the National Academy of Sciences (1985)

• Tomalla Foundation Prize (1987)

• Magellanic Premium (1990)

• Albert Einstein Medal (1991)

• John J. Carty Award for the Advancement of Science of the National Academy of Sciences (1991)

• Wolf Prize in Physics (1992)

• Nobel Prize in Physics (1993)

• Karl Schwarzschild Medal (1997)

• World Radiocommunication Conference (WRC-12) Address (2012)

• International Telecommunication Union (ITU) Gold Medal (2012)

• ARRL Centennial Presentation (2014)

The Radio Club of America would like to particularly thank RCA President Tim Duffy for his role in inviting Professor Taylor to join us at the 2016 banquet. We look forward to seeing everyone in November for this rare and very exciting opportunity.

Lifetime Achievement Award: Dr. Joseph H. Taylor, K1JT — For significant achievements and a major body of work accomplished over a lifetime that has advanced the art and science of radio and wireless technol-ogy. Dr. Taylor, a Princeton University Professor, is a lifetime amateur radio

operator. He and Russell Hulse received the Nobel Prize in Physics in 1993 for their discovery in 1975 of the first binary pulsar system. Their discovery confirmed Albert Einstein's theories about the existence of gravita-tional waves 100 years after they first were published. Over more than 30 years, Dr. Taylor led, established, defined, and honed a team of radio astronomers that designed state-of-the-art radio technology for detection and timing of pulsed radio radiation from neutron stars. Dr. Taylor showed that radio could be used to detail and prove a fundamental aspect of nature (general relativity), thereby placing radio technology in the top tier of impor-tance in contemporary science. A related biography and reprint of Dr. Taylor’s 2004 paper revisiting his discover-ies and progress in his field can be found in this issue of the Proceedings.

Armstrong Medal: Morgan E. O’Brien — For outstanding achievements and lasting contribu-tions to the radio arts and sciences and wireless communications. As the co-founder and chairman of Nextel Communications, Inc., O’Brien led the creation of the first all-digital na-

tionwide wireless network (the Nextel National Network) using IDEN technology and brought push-to-talk (PTT) communication to the mass business and consumer market. Since that time he co-founded Cyren Call Com-munications (where he served until January 2009), has been a consultant to wireless start-ups, and has served on the board of several private companies and charita-ble organizations. Mr. O’Brien was recognized in 1987 as New Jersey Entrepreneur of the Year and was voted the RCR Person of the Year in 1993 and again in 2006. In 2005, he was inducted into the Washington, D.C. Business Hall of Fame. He is a Fellow of the Radio Club

of America and was named by Fierce Wireless as “one of the top U.S. wireless innovators of all time.” He current-ly serves as the Vice Chairman of the Board of Directors for pdvWIRELESS. O’Brien developed the initial plan for a nationwide broadband communications network for first responders, which eventually morphed into the Nationwide Public Safety Broadband Network (NPSBN) that is being developed under the auspices of the First Responder Network Authority (FirstNet).”

Sarnoff Citation: William T. Murphy, W0RSJ — For exceptional contributions of a tech-nical or non-technical nature to the advancement of electronic commu-nications. Mr. Murphy, an active amateur radio operator for more than 50 years, currently specializes in

business continuity, disaster recovery, and emergency communications, and is a licensed Certified Business Continuity Professional. Most of his career was spent with AT&T, from which he retired in 1999 after serving in many capacities. He is responsible for developing methods and apparatus to verify the integrity of commu-nications facilities leased from other networks. He was inducted into the New Jersey Inventors Hall of Fame for his work in performance monitoring for leased transmis-sion facilities and disaster recovery.

Henri Busignies Memorial Award: Dr. Mischa Schwartz — For achieve-ments in the field of communications equipment and contributions to the advancement of electronics for the benefit of humanity. Dr. Schwartz is the Charles Batchelor Professor Emeritus of Electrical Engineering at

Columbia University, where he was the founding Director of the National Science Foundation-sponsored Center for Telecommunications Research (CTR). He received a BEE from the Cooper Union, New York, an MEE from the Polytechnic Institute, and a Ph.D. degree in Applied Physics from Harvard University. Prior to joining Colum-bia in 1973, he was Professor of Electrical Engineering and the Department Head at the Polytechnic Institute of Brooklyn and a Project Engineer at Sperry Gyroscope

The 107th Radio Club of America Awards Banquet will take place at the New York Athletic Club on November 18. Numerous individuals will receive recognition for their contributions to the industry and to the RCA. One of the hallmarks of the RCA Proceedings has been to provide background about our award recipients to celebrate their achievements. Congratulations to all of our award recipients. We encourage everyone to plan on attending the 2016 banquet to meet these and other outstanding members of our illustrious club.

14 FALL 2016 PROCEEDINGS | www.radioclubofamerica.org

This year we have another very interesting Technical Symposium, with another “Wireless Wow,” found only with RCA!

Our Wireless Wow for this year’s Technical Symposium is a presentation by Professor Tom Perera. Professor Perera has spent much of his professional career search-ing for German World War II Engima cipher-coding machines—even though Winston Churchill at the end of the war said they all had been destroyed! Most of the German Enigma-encoded messages were carried on wire-less to the U-boat submarine fleet, or to German army units. Breaking the code was vital to the Allies winning the war, and the machine has been featured in two films, Enigma and The Imitation Game. Professor Perera has a unique collection of rebuilt and working Enigma machines, and he will bring one to display at our event!

Our agenda for this year is an exciting one, with unique topics that you will only find in RCA’s Technical

Symposium, such as software-defined radios (SDR) for the military, radio access network (RAN) hardware that allows for rural deployments of Long-Term Evolution (LTE) broadband services, and a historical presentation about the legendary Edwin H. Armstrong.

This year, we also have two panels of experts discussing timely wireless topics including 5G, and in-building wire-less for both cellular and public safety.

For those who are registered professional engineers (PEs), or others who require CEUs (Continuing Education Units), attendees can obtain a certificate from a recognized university attesting to the CEUs they have received, for a modest fee (note that RCA makes no money on this endeavor—this is for the convenience of our members who are PEs).

The agenda is below, followed by abstracts on the presentations, and then detailed bios on the speakers and panelists.

8:15 – 9:00 a.m. — “Developing Secure Tactical Multi-Role, Multi-Mission, Multi-Channel Radios with Increasing Demands for Data Everywhere,” (Harris Corp.)

This presentation will explore some of the complex tradeoffs encountered in the design and development of military tactical radios using a software-defined radio (SDR) architecture. As the need for more and more situational awareness is pushed all the way to the indi-vidual on the battlefield, radios increasingly are required to implement a much richer feature set of capabilities, while still being constrained by size, weight and power. The radio frequency (RF) section(s) must enable wide bandwidth and high-data-rate capabilities, but in their multi-role application also must support narrowband as well as advanced counter-measure capabilities. In all cases, these radios must provide the highest level of information security and meet very high environ-mental specifications. Maximizing capabilities across these varied requirements involves leveraging the latest technologies, as well as incorporating decades of com-munications experience gained from iteratively improved designs that have been successfully utilized over the last 40 years.

9:00 – 9:45 a.m. — "Removing Economical Constraints of Rural Deployments with RAN hardware Innovation"

This session will explain how cellular network operators can use new software-defined network (SDN) architec-tures to help simplify network build out and reduce maintenance costs, while connecting hard-to-reach areas. The speaker from Parallel Wireless will discuss how the company has developed and deployed (in the United Kingdom, U.S. and Asia) a unique low-cost rural solution, nominated by Global Mobile Awards by GSMA as a finalist for Best Mobile Technology Breakthrough of 2014. It brings 3G/4G to areas that previously had no coverage – all at a fraction of the cost.

Session attendees will benefit from exploring how the solution solves the challenges of delivering cost-effec-tive backhaul connections with wireless and satellite backhaul. They also will learn how this technology helps manage the complexity between the access side and the evolved packet core (EPC) sides of the network, while making the radio access network (RAN) self-con-figurable, self-optimizing and self-healing, all of which reduces installation and maintenance costs.

10:00 – 10:45 a.m. — “Major Edwin H. Armstrong: Student Inventor to Great Radio Engineer”

This session describes Armstrong’s many great contri-butions to radio: first, while an electrical engineering student at Columbia University, and shortly thereafter while with the U.S. Army Signal Corps during WWI, and then much later on, while an unpaid electrical engineer-ing professor at Columbia. His first set of contributions led, in a major way, to AM radio. His latter contributions led to the invention of low-noise FM in 1933, resulting in the widespread adoption of FM radio.

10:45 – 11:30 a.m. — “Youth Presentation on Wireless: Reactive to Proactive, Using the Raspberry Pi Computer to Build a Home Sensor Network”

Presenter Divyam Mishra’s idea of building a home sensor network first emerged during his research at the University of Colorado at Boulder. This network includes a Raspberry Pi that acts as a centralized computer that both collects data and evaluates the data, a plethora of Arduino microcontrollers that have temperature sensors attached to them, and a wireless 422 MHz transceiver. Currently, this is just a basic prototype. The product is intended to transform our lives from reactive to proactive by predicting problems with our devices ahead of time. For example, if there is a problem with a heater, then the customer will be notified of a possible furnace failure in the future. Initially, Divyam implemented a basic system where data is gathered and sent to a cloud-storage cli-ent. Now he is focusing on making a phone application that can show the customer the potential problems with the temperature distribution in the house via augmented reality. If for some reason the temperature exceeds a certain temperature (indicating a possible fire), radi-os will be used to communicate to first responders in a matter of seconds. This will require the integration of Raspberry Pi computers and radios in a way that is revolutionary. This project ended up becoming a product named ProBoT.

11:30 am – 12:15 p.m. — “Progress Report on RCA's Youth Initiative”

All of us in wireless realize that our industry is going through a “graying phase,” and the industry is in desper-ate need of a new generation of technicians, engineers, scientists, and other wireless-savvy professionals to lead the next wave of wireless progress. Carole Perry, an RCA Director, and Chair of our youth program, will update us on the progress of her vital endeavors.

1:15 – 2:00 p.m. — “Panel 1: 5G – What, Why, and When”

The wireless industry hype on Fifth Generation (5G) cellular systems has continued, even though 4G LTE sys-tems are not completely built out yet among the major public carriers. But what is 5G? When the standards are still in flux, why does the industry need this technology, and when will it begin to be implemented? The pan-el will address all of these issues with experts that are helping to make 5G a reality. This panel is moderated by Andy Seybold, the well-known wireless industry pundit.

3:00 – 3:45 p.m. — “Panel 2: In-Building Communications”

As smart devices proliferate, the demand for “data everywhere” is driving the cellular carriers to expand their networks both in terms of overall data capacity and “coverage everywhere.” Further, carriers are evolving to meet the increasing data demands by offloading from the macro outdoor sites to in-building systems.

In addition, the public expects first responders (police, EMS, fire) to go into any building and provide immediate aid regardless of how difficult that location may be from an RF propagation standpoint. In recent years, in-build-

ing wireless systems have been built out in major venues such as sports stadiums, either by the cellular carriers or the venue owners. But now a “middle tier” of office buildings, apartment complexes, and smaller entertain-ment venues need to be built out. It is not clear who will pay for this, and how and when it will be accomplished. Our panel of experts, including consultants and vendors, will examine these difficult issues occurring in the next stage of build out, and provide some insights. This pan-el is moderated by Rob Lopez, P.E.

3:45 – 4:30 p.m. — "Inside Enigma: Breaking the Top-Secret Enigma Codes of WWII"

During World War II, the German military used Enigma cipher machines to encode all of their important wireless and wired communications. The breaking of these Enig-ma codes by Allied forces is credited with shortening the war by two years, saving thousands of lives, and perhaps keeping Adolph Hitler from developing the atomic bomb. This session will explain how the Enigma works and trace the fascinating history of the cracking of the Enigma codes. The real story behind the Imitation Game movie will be explained. A working Enigma machine will be on display outside the Technical Symposium presentation room.

THE WORK OF DR. JOE TAYLOR AND AN INTERVIEW WITH DR. JOEL WEISBERG By Dr. Nathan “Chip” Cohen and David Bart

EDITOR'S NOTE: Dr. Joseph Taylor will receive the Radio Club of America’s Lifetime Achievement Award at its November 18, 2016 banquet and awards ceremony. The following article describes Dr. Taylor’s key discovery and includes an interview with one of his collaborators, Dr. Joel Weisberg. This article is followed by a reprint of an article written by Drs. Weisberg and Taylor summarizing their work.

Dr. Joseph (“Joe”) Taylor (K1JT) is a Princeton based radio astronomer and astrophysicist with considerable expertise. He is widely recognized

for his successes in radio science. He is best known for discovery, long-term measurements, analysis, and conclusive support for the theory of general relativity through radio measurements of a binary pulsar system.

THE DISCOVERYOver more than 30 years, Dr. Taylor led, established, defined, and honed a team of radio astronomers that designed state-of-the-art radio technology for detection and timing of pulsed radio radiation from neutron stars. The binary pulsar P1913+16(see below) was especially rich in this regard, as the radio measurements proved and detailed the decay of orbits in the binary system, these decays were caused by loss to gravitational waves radiation. This was the first conclusive evidence for gravitational radiation and this evidence supported a key and unique aspect of Einstein’s theory of general relativity. These measurements and analysis would not have been accomplished without Dr. Taylor’s efforts, perseverance, and expert knowledge of radio and physics.

Dr. Taylor showed that radio could be used to detail and prove a fundamental aspect of nature (general relativity), thereby placing radio technology (again) in the top tier of importance in contemporary science.

The discovery of this binary pulsar was made at the Arecibo Observatory’s 305m antenna, the giant radio dish in Puerto Rico. Dr. Russell Alan Hulse and Dr. Taylor, then at University of Massachusetts, sought and detected pulsed radio emissions as part of a new survey of the skies. They identified an unusual pulsar, a rapidly rotating, highly magnetized neutron star. This neutron star rotates on its axis 17 times per second; hence the pulse period is 59 milliseconds. By timing the radio pulses over a lengthy period they observed a systematic variation in the arrival time of the pulses; some received sooner than expected and others later than expected. These variations changed in a smooth and repetitive manner, with a period of 7.75 hours. They realized that such behavior is predicted if the pulsar were in a binary orbit with another star, later confirmed to be another neutron star. The pulses from the pulsar arrived 3 seconds earlier at some times relative to others, showing that the pulsar’s orbit is 3 light-seconds across, approximately two-thirds of the diameter of the Sun. Since this is a binary system, the masses of the two neutron stars can be determined from Kepler’s laws: each neutron star is around 1–3 times the mass of the Sun.

NOBEL PRIZEToday, PSR B1913+16 (also known as PSR J1915+1606 and PSR 1913+16) is referred to as the ‘Hulse–Taylor binary’, named after its discoverers. It was the first binary pulsar to be discovered. The discovery of the system and analysis earned Drs. Taylor and Hulse the 1993 Nobel Prize in Physics “for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation.” (Nobel Foundation)

This binary pulsar acts as a scientific laboratory for understanding neutron stars and the evolution of stars. But in addition, observations have since shown that the pulsar’s orbit is gradually contracting as it orbits its companion. This posed great excitement to physicists, as Albert Einstein’s general relativity had made very specific predictions that orbiting stars will lose energy over time to gravity waves—gravitation radiation—and that as they lose this energy, their orbits will get tighter and the orbital periods would decrease. Because the binary pulsar executes on orbital round in less than eight hours, monitoring the pulsar orbits over a period of

many years should clinch the evidence—or denial—of gravitational radiation. To wit: was Einstein right?

Dr. Taylor, through the collaboration of many researchers, but especially through his colleague Dr. Joel Weisberg, sought to undertake these observations needed to check Einstein. Not an easy task, as special tools had to be built to time and decipher minute changes in the radio pulses, and to compare changes over the course of decades.

Drs. Hulse and Taylor were awarded the Nobel Prize for the discovery of the binary pulsar, but the conclusive and overwhelming evidence of gravitational radiation took over thirty years, and continued long after their award. The accuracy needed to overwhelmingly prove Einstein was reported in 2004 and 2005 by Dr. Joel Weisberg and Dr. Taylor to be within 0.2% of that predicted by general relativity. Drs. Weisberg and Taylor summarized their work in their paper “Relativistic Binary Pulsar Bl913+16: Thirty Years of Observations and Analysis” published by the Astronomical Society of the Pacific in 2004 and 2005. The paper summarized the state of work in the field up to that time, and key publications are referenced therein.

INTERVIEW WITH DR. WEISBERGDr. Taylor has been generous to collaborators in sharing recognition with them (such as Hulse and Weisberg), and is often listed as the last author on publications that predominantly stem from his efforts. Both Hulse and Weisberg were graduate students when they initially worked with Taylor, then a professor at University of Massachusetts.

In connection with RCA’s recognition of Dr. Taylor’s contributions, Chip Cohen and David Bart interviewed Dr. Weisberg about his experiences working with Joe Taylor. The following interview is reproduced herein for our readers.

How did you first meet Joe Taylor and begin working with him; what problems were you both interested in investigating and why?

[Dr. Weisberg] As I was finishing my Ph.D. in pulsar astrophysics, I wrote him to ask if he might have a postdoctoral position for me. Later, I flew out to meet him, and was immediately struck by his warmth and kindness and expertise in pulsars. We were both deeply fascinated by these incredible objects, and also shared many larger values.

Can you tell us about the binary pulsar—what caused it, how big is it, how far away is it? Can you see it with an optical telescope, or is this enabled by radio?

[Dr. Weisberg] A pulsar is the collapsed remnant of a cataclysmic supernova explosion, composed of neutrons, weighing more than the Sun, the size of a city, and spinning on its axis up to hundreds of times per second, with a beam of radio waves on one side. We detect a radio pulse once per rotation when the beam points as us, much like a lighthouse. A binary pulsar is a pulsar orbiting another object, in this case another neutron star, born in a separate supernova explosion. The system is about 30,000 light years away; still in our Milky Way Galaxy, but not particularly close. Most pulsars, including this one, emit mainly in the radio.

Treating a pulsar as a clock, a pulsar in a binary star will change its timing, speeding up and slowing down slightly as it orbits its companion; how did you use that

to show that the orbit was changing from the energy loss of gravitational radiation?

[Dr. Weisberg] I couldn’t say it better myself! We time the arrival of its pulses with a precision of about ten millionths of a second for each five minutes of data accumulated. We can then map out the orbit very precisely - when the pulsar is on the near side of its orbit, the pulses come in several seconds early, and so on. With patient observations over many years, we were able to see the orbit shrinking at just the rate expected if energy were carried away by gravitational radiation.

Can you describe the pulsar timing machine you built with Joe and how it works?

[Dr. Weisberg] Joe is a master of building pulsar timing machines. His origin as a ham was no doubt crucial to this, along with his brilliance. A succession of these devices, when coupled to the Arecibo telescope, formed the heart of numerous pulsar experiments for many years. My own role in constructing these machines was minimal.

It took considerable patience to wait out such small changes. When did you, Joe and others feel you had clinched the evidence showing Einstein was right on gravitational radiation?

[Dr. Weisberg] Literally—when the evidence was incontrovertible that the orbit was shrinking at the predicted rate.

A decade ago you and colleagues reported another remarkable event—a natural maser magnifying a background pulsar. What did we learn from that?

[Dr. Weisberg] While there was previously much indirect evidence of interstellar masers, this was the first time anyone caught a maser switching on and off as the pulsar beam excited it and then turned away.

Young people often see science as overly serious. Tell us about the fun you had, both in discovery, and understanding the binary pulsar.

[Dr. Weisberg] We have plenty of fun! We use incredible, inspiring instruments such as the Arecibo radio telescope. We work with very bright, clever, and creative people. We get to expand ours’ and all humans’ understanding of the universe. What’s not to like?

Radio astronomy is now seeing some tough times, even though it is only roughly 80 years old. How do we teach young people to understand the inevitable discoveries that are bound to happen in the next 80 years with radio science, and give society the patience to look long term?

[Dr. Weisberg] We can try to reach out to these young people through all kinds of educational activities. Most people have natural curiosity about the heavens, which helps them to be open to the message.

Do you have any additional thoughts about working with Joe Taylor?

[Dr. Weisberg] He is a brilliant person, who is a pleasure to work with.

Dr. Joel Weisberg at Carleton College.

The Relativistic Binary Pulsar B1913+16: Thirty Years ofObservations and Analysis

Abstract. We describe results derived from thirty years of observations ofPSR B1913+16. Together with the Keplerian orbital parameters, measurementsof the relativistic periastron advance and a combination of gravitational redshiftand time dilation yield the stellar masses with high accuracy. The measuredrate of change of orbital period agrees with that expected from the emissionof gravitational radiation, according to general relativity, to within about 0.2percent. Systematic effects depending on the pulsar distance and on poorlyknown Galactic constants now dominate the error budget, so tighter boundswill be difficult to obtain. Geodetic precession of the pulsar spin axis leads tosecular changes in pulse shape as the pulsar-observer geometry changes. Thiseffect makes it possible to model the two-dimensional structure of the beam.We find that the beam is elongated in the latitude direction and appears to bepinched in longitude near its center.

1. Introduction

Pulsar B1913+16 was the first binary pulsar to be discovered (Hulse & Tay-lor 1975). Thirty years of subsequent observations have enabled us to measurenumerous relativistic phenomena. We have used these measurements for funda-mental tests of gravitational physics and to place tight constraints on physicalparameters of the system. In this paper, we provide the latest results of ourobservations and analysis.

2. Observations

The observable pulsar is a weak radio source with a flux density of about 1mJy at1400 MHz. Its observations are nearly always sensitivity limited. Over the yearswe and our colleagues have built a number of sensitive receiver “back ends” foruse at Arecibo, including a swept local-oscillator system programmed to followthe dispersed pulse, as well as filter banks and signal averagers (see Weisberg& Taylor 2003 for a summary). Our most recent data have been gathered withthe Wideband Arecibo Pulsar Processors (“WAPPs”), which for PSR B1913+16

achieve 13µs time-of-arrival measurements in each of four 100MHz bands, using5-minute integrations. In addition to the timing observations, we have usedthe Princeton Mark IV coherent de-dispersing system (Stairs et al. 2000) tomeasure average pulse shapes and polarization over the last five years. A majorimprovement in data acquisition for this experiment was made in 1981, and datataken since then have much higher quality than the earlier observations. Theresults reported here are based largely on data gathered from 1981 through 2003.

3. Relativistic Timing Analysis

Non-relativistic analysis of arrival time data from this system can yield fiveorbital parameters: the projected semimajor axis of the pulsar orbit ap sin i,orbital eccentricity e, epoch of periastron T0, orbital period Pb, and argumentof periastron ω0. Relativistic effects lead to three additional measurables: themean rate of advance of periastron 〈ω〉, gravitational-redshift and time-dilation

parameter γ, and orbital period derivative Pb. Measured pulse times of arrivalcalculated for each five minutes of observation serve as the input data for theprogram TEMPO (http://pulsar.princeton.edu/tempo). This program fitsa model with eighteen parameters (eight orbital quantities plus ten astrometricand spin parameters) to the data, using the timing model of Damour & Deruelle(1985; 1986). Fitted values for the orbital parameters are listed in Table 1, withuncertainties in the last shown in parentheses.

The pulsar orbit is fully specified (up to an unknown rotation about the line ofsight) by the first seven parameters listed in Table 1. Other orbital quantitiessuch as inclination, masses of the stellar components, and the semimajor axes,may be derived from these seven; Taylor & Weisberg (1982) provide the relevantformulas. For example, the masses of the pulsar and companion are mp =1.4414± 0.0002 and mc = 1.3867± 0.0002 solar masses, respectively. (Note thatin order to express the masses in grams, a value would need to be introduced forthe Newtonian gravitational constant G. The uncertainty in G is comparableto our quoted uncertainties in mp and mc.) As described below, the eighth

measured orbital parameter, Pb, overdetermines the system dynamically andthus provides a test of gravitation theory.

The Relativistic Binary Pulsar B1913+16 27

3.1. Emission of Gravitational Radiation

According to general relativity, a binary star system should emit energy in theform of gravitational waves. The loss of orbital energy results in shrinkage ofthe orbit, which is most easily observed as a decrease in orbital period. Peters& Matthews (1963) showed that in general relativity the rate of period decreaseis given by

Pb,GR = −192 π G5/3

5 c5

(Pb

)−5/3

(1 − e2)−7/2 × (1)(

1 +73

24e2 +

37

96e4

)mp mc (mp + mc)

−1/3.

Note that except for Newton’s constant G and the speed of light c, all quantitieson the right hand side of Eq. (1) have measured values listed in Table 1, or,in the case of the component masses, are derivable from those quantities. Thepredicted orbital period derivative due to gravitational radiation computed fromEq. (1) is Pb,GR = −(2.40242 ± 0.00002) × 10−12 s/s.

Comparison of the measured Pb with the theoretical value requires a small cor-rection, Pb,Gal, for relative acceleration between the solar system and binarypulsar system, projected onto the line of sight (Damour & Taylor 1991). This

correction is applied to the measured Pb to form a “corrected” value Pb,corrected =

Pb − Pb,Gal. The correction term depends on several rather poorly known quan-tities, including the distance and proper motion of the pulsar and the radiusof the Sun’s galactic orbit. The best currently available values yield Pb,Gal =

−(0.0128 ± 0.0050) × 10−12 s/s, so that Pb,corrected = (2.4056 ± 0.0051) × 10−12

s/s. Hence

Pb,corrected

Pb,GR

= 1.0013 ± 0.0021, (2)

and we conclude that the measured orbital decay is consistent at the (0.13 ±0.21)% level with the general relativistic prediction for the emission of gravi-tational radiation. The observed and theoretical orbital decays are comparedgraphically in Figure 1.

Accuracy of the test for gravitational radiation damping is now dominated by theuncertainty in the galactic acceleration term. Work now underway should leadto improved accuracy of the pulsar proper motion, and the Sun’s galactocentricdistance may be better known in the future. However, we see little prospect fora significant improvement in knowledge of the pulsar distance. Consequently, itseems unlikely that this test of relativistic gravity will be improved significantlyin the foreseeable future.

The Relativistic Binary Pulsar B1913+16 29

this so-called “geodetic” precession has a period of about 300 y. The resultingchange of aspect with respect to the line of sight should cause a secular changein pulse shape. Weisberg, Romani, & Taylor (1989) reported shape changes at1400 MHz and attributed them to the line of sight moving across the middle ofa hollow-cone beam. Kramer (1998) found that the separation between the twoprincipal pulse components began to shrink in the mid-1990s, suggesting thatthe line of sight had continued to drift across the conal beam, moving fartherfrom its center. Kramer fitted a model to these data, which indicated that thepulsar spin and orbital angular momenta are misaligned by ∼ 20◦ and that thebeam will no longer intersect our line of sight after the year 2025. Weisberg &Taylor (2002) confirmed these results and found that the conal beam appears tobe elongated in the direction parallel to the spin axis; they also noted that thebeam appears to be “hourglass-shaped,” or pinched in longitude near its center(see Fig. 2). Kramer (2002) argued that these observations could also resultfrom the line of sight precessing away from the center of a circular emission coneand onto a core pencil beam that is offset below the center and toward the thetrailing part of the cone.

We divided all of our 1400 MHz profiles into components that are respectivelyeven and odd about the profile center. We then fitted the even components to amodel that allows for a noncircular conal beam (Weisberg & Taylor 2002). Withmore data now available, we find that the model parameters have changed littlefrom earlier solutions. The current model is illustrated in Figure 2 in the formof equal-intensity contours of the beam.

Rankin (1983) showed that in most pulsars core emission becomes more promi-nent at low frequencies. We have observed PSR B1913+16 at the lower frequencyof 430 MHz at several epochs, and three of the resulting pulse profiles are shownin Figure 3. A core component is quite prominent in the data taken in 1980-81,but it faded very significantly between 1980 and 1998 and was nearly gone by2003. This behavior further supports our model in which the line of sight is pre-cessing away from the axis of a centered pencil beam plus a longitude-pinchedcone elongated in the latitude direction.

Even with 30 years of observations, only a small portion of the North-Southextent of the emission beam has been observed. As a consequence, our model isneither unique nor particularly robust. The North-South symmetry of the modelis assumed, not observed, since the line of sight has fallen on the same side ofthe beam axis throughout these observations. Nevertheless, accumulating datacontinue to support the principal features noted above.

On October 7, 2016, Dr. Theodore (Ted) Rappaport of NYU WIRELESS (RCA Fellow and RCA Armstrong Medalist) gave a major speech in New

York City demonstrating that millimeter wave (mmWave) wireless communications work in rural settings.

Dr. Rappaport detailed the research, conducted in the summer of 2016, in which NYU WIRELESS analyzed the viability of line-of-sight (LOS) and non-line-of-sight (NLOS) transmission of mmWave radio for rural settings. NYU WIRELESS used these statistics to generate the first-ever rural path loss model for mmWave frequencies at 73 GHz, demonstrating the remarkable distances that can be achieved using mmWave. Dr. Rappaport, NYU Tandon professor of electrical engineering and founding director of NYU WIRELESS, presented the research, including measurements and models at the Association of Computing Machinery (ACM) MobiCom “All Things Cellular” workshop in New York City.

On July 14 of this year, the FCC voted unanimously on the historic Spectrum Frontiers plan to free up unprecedented amounts of radio bandwidth for unlicensed Wi-Fi access and a new, fifth generation (5G) of wireless communication. The move effectively quadruples the amount of radio bandwidth ever before available to the mobile industry. It also will reduce the cost and complexity of bringing Internet service to

underserved rural areas. Wireless carriers are looking at mmWave as an avenue for rural delivery of 5G wireless Internet service. Dr. Rappaport demonstrated that the approved Third Generation Partnership Project (3GPP) channel model standard—3GPP TR 38.900 (version 14)—has an error in its rural macrocellular model, making it unusable above 9.1 GHz. That 3GPP model never was verified with measurements. He detailed how an errant model made its way into the current 3GPP standard, and then offered a proven model that can be used for rural deployments at all frequencies.

The paper, “Millimeter Wave Wireless Communications: New Results for Rural Connectivity,” appears in All Things Cellular '16, published in conjunction with the ACM MobiCom conference on October 7, 2016. Authors include: George R. MacCartney Jr., Shu Sun, Theodore S. Rappaport, Yunchou Xing, Hangsong Yan, Jeton Koka, Ruichen Wang, and Dian Yu. A link to the complete paper is available from the Cornell University Library at: https://arxiv.org/abs/1608.05384.

The paper is highly technical. Dr. Rappaport also provided a link to the complete presentation discussing his team’s findings, which is available at: http://wireless.engineering.nyu.edu/presentations/Rural-Macrocell-path-loss-NYU-Al-things-cellular-Oct-7-2016.pdf.

Ted Rappaport holds the David Lee/Ernst Weber Chair in the Electrical and Computer Engineering

Department of the NYU Polytechnic School of Engineering, as well as faculty appointments at Courant and the Department of Radiology at NYU Langone School of Medicine. NYU WIRELESS is a multi-disciplinary academic research center the Brooklyn engineering location providing a world-class research environment that is creating the fundamental theories and techniques for next-generation mass-deployable wireless devices

The center uniquely combines expertise from NYU’s Tandon School of Engineering, School of Medicine, and Courant Institute of Mathematical Sciences supporting the creation of new wireless circuits and systems as well as new health care solutions for the wireless industry. For more information, visit http://nyuwireless.com.

The key conclusions reached to date are as follows:

• mmWave communication links will be useful to rural distances greater than 10 kilometers (km) rural macrocell (RMa).

• Existing 3GPP LOS RMa path-loss models are not proven, and revert to a single slope model above 9.1 GHz due to

the breakpoint. The close-in (CI) path-loss model is simple, accurate and verified. Further work will include a factor in the path loss exponent PLE for transmit (TX) height.

Dr. Rappaport proposes to replace the existing 3GPP and International Telecommunication Union (ITU) RMa models, or make the CI RMa path-loss models optional. They

are based on measurements, applicable from 1 meter to 12 km, and frequencies of 500 MHz to 100 GHz, that should be increased, bringing to 4 or 8 decibels (db) (LOS/NLOS) to match current TR 38.900 3GPP RMa . The 3GPP and ITU RMa models with the proposed replacements in parameters are shown below:

THE FIRST POCKET RADIO PAGER: FROM INCEPTION TO OBSOLESCENCE(THEY DIDN’T ALWAYS GO BEEP BEEP)By Michael Clarson

It was the mid 1970s, and my first exposure to radio paging was as a technician with Motorola at their Springfield, N.J., shop. There were Pageboy I and IIs,

and the occasional Handie Talkie Pager form the early 1960s. All of these units were selectively alerted so a message only would get to the desired user. Several years later, I was on the corporate engineering team for Airsignal International, Inc., one of the first, if not the first, paging companies with operations across this country and beyond.

As a curious person, I was interested in the company’s history. Airsignal was formed when investors bought up several marginal paging operations, along with their associated telephone answering services, across the country. Many of these paging operations used Amplitude Modulation (AM) for paging, and they used a Florac device to get messages to subscribers. The company’s goal was to convert these systems from the 1950s into state-of-the-art Frequency Modulation (FM) systems with selective call pagers made by NEC to under-price their competitors who were using Motorola products. Although this was a good strategic plan, many state Public Utility Commissions would not let Airsignal discontinue Florac service.

FLORACThe obvious question is “What is a Florac?” A pager, of course. In the 1940s, FM broadcast radio was in its infancy. Radio Club of America (RCA) member Edwin H. Armstrong had his stations on 41 MHz, and the FCC opened a new band between 88 and 108 MHz to fit in television frequency allocations. Still, there was one major advantage that those using AM Broadcast had that FM broadcasters did not possess, and that was the use of portable radios. A small company, “Richard R. Florac Ultra Miniature Electronics,” made a pocketsized radio with two subminiature tubes (Figure 1). The radio operated on a Super-Regenerative design, a method of detection invented by Armstrong in the 1920s that was extremely sensitive, simple, worked well on FM and AM alike, but was not very selective. Amateur radio operators from the 1960s might remember the Heathkit Twoer which used this detector on the 144 MHz Amateur band.

THE FLORAC PAGERIn the late 1940s, an established telephone answering service in New York, Telanserphone, sought a way to reach its subscribers when they were not near their phone. A device like the Florac FM portable seemed to be the right solution. Florac developed a two-tube pocket-sized radio pager that could hear an AM transmitter on 43.58 MHz (Figure 2). In 1950, the first radio page to a pocket receiver was completed (Figures 3 and 4). Here is how it worked. Each subscriber was assigned a three-digit number. When a message came in, the operator received the message and recorded the three-digit number on a tape loop, and this loop would play continuously on the transmitter for a specified period of time, typically 15 minutes. Periodically, the subscriber would check for messages by taking the receiver out of his pocket, pressing the ON switch, letting the tubes warm up, holding the unit to his ear, tuning in the transmitter and listening for his number. If his number was announced, he would find a telephone, call the service and get the message. What could be more convenient?

By the mid 1950s, the FLORAC evolved into a slightly smaller solid-state design made with three transistors, eliminating the warmup time and improving battery life. It still had an aluminum case and the noodle wire antenna.

AIRSIGNALFast forward to 1970, and the Bogen 250-watt AM transmitters were becoming unreliable, but the Floracs were still being used. When Airsignal, Inc. purchased some of these systems and was required to maintain service, they sought a manufacturer of AM transmitters. Philadelphia used a transmitter made by Amcor (Figure 5), a paging terminal manufacturer. It ran 350 watts, to a pair of 4-125 tubes modulated by another pair of 4-125s. It was reliable, but was not upgradable to the more modern FM systems. I believe it was the only one in existence.

Airsignal attempted to obtain an AM transmitter that was upgradable to FM and contacted Motorola, General Electric, and Gates Broadcasting, with no success. Shortly after contacting Gates, a Gates engineer offered to build a transmitter for Airsignal if the company would order 10 of them. They did, he did, and the Quintron QT-350 was born. It operated on either AM or FM, on remote command, and could run 350 watts 24 hours a day. And so, FLORACs held onto their market for a few more years.

The Radio Club of America (RCA) has embarked on an initiative to partner with numerous critical and prestigious organizations in the wireless industry,

thanks to the efforts of Director John Facella. These partnerships are very much in synchrony with RCA's broader goals and efforts: getting youth interested in wireless through amateur radio; our college scholarship program; providing continuing professional engineering and technical training through our Technical Symposium and a new program which will be announced soon; offering opportunities for professional networking; and historical preservation.

RCA’s partnership program involves signing a memorandum of understanding (MOU) with each partner whereby RCA and the partner agree to provide improved benefits to the other organization’s members. Benefits to members vary depending on the partnership agreement, and details can be found on each organization’s website.

Our first partnership agreement was executed with the Electronic Technicians Association (ETA). ETA is well known in the wireless industry for providing vital training and credentialing to technical personnel who develop, install, maintain, and troubleshoot wireless systems. RCA also has entered into partnership agreements with APCO International, the Antique Wireless Association, IWCE, and the U.S. Navy Cryptologic Veterans Association. Several other partnerships are expected to be announced in the future.

Brief descriptions of our new organizational partners are as follows. We welcome all of them to RCA!

The Association of Public-Safety Communications Officials International (APCO) is a member

driven association of communications professionals that provides leadership; influences public safety communications decisions of government and industry; promotes professional development; and, fosters the development and use of technology for the benefit of the public. www.apcointl.org.

The Antique Wireless Association was formed in 1952 and is an educational non-profit organization chartered by the State of New York. AWA operates the Antique Wireless Museum in Bloomfield, New York, dedicated to preserving and

sharing the history of technology used to communicate and entertain from the first telegram to today’s wireless text messaging. AWA Deputy Director Robert Hobday said, “The AWA believes the Memorandum of Understanding (MOU) with RCA will open avenues to new or existing members for both organizations, and we are excited to partner with RCA.” RCA President Tim Duffy said, “RCA Director Dave Bart saw the potential in this partnership, because both of our organizations believe in honoring the past in order to ensure the future of the wireless industry.” Visit AWA on Facebook or at their website: www.antiquewireless.org.

Since 1978, ETA has delivered over 200,000 professional certifications. ETA certifications are widely recognized and frequently used in worker job selection, hiring processes, pay increases, advancements, and often required as companies

bid on contracts. ETA's certifications are personal and travel with the individual, regardless of employment or status change and measure competencies of persons, not products or vendors. All ETA certifications are accredited through the International Certification Accreditation Council (ICAC) and align with the IS0-17024 standard. For more information, visit www.eta-i.org.

The Radio Club of America regularly celebrates its historic ties to the legendary Maj. Edwin Howard Armstrong. Typically, we remember his four

major inventions: regeneration, super-regeneration, the superheterodyne, and frequency modulation. In addition, Armstrong directly influenced the development of early portable radios.

As the commercial radio boom exploded in 1922, numerous companies began to promote the portability of their radio sets. The Radio Corporation of America ("RCA" in this article) was not alone in bringing out a small, portable set that provided a headset for the listener and which required a separate antenna and separate battery power source. But what about speakers so that the sound could be reproduced for a room full of listeners, and could the antenna be incorporated into the radio? RCA would seize on publicity surrounding Armstrong’s new marriage to develop and help popularize a newly designed, fully functional, self-contained portable set.

1922-1924 SUPERHETERODYNESBy October 1922, Western Electric (WE) engineers had developed a seven-tube superheterodyne Model 4A receiver for AT&T that filled a table to operate. RCA’s Director of Research, Dr. Alfred N. Goldsmith, was shown the radio. Progress in the circuits aside, the radio’s size and configuration were typical for its time; it required separate batteries, antenna, circuit box and headphones to operate, as well as some knowledge and skill by the radio enthusiast. Meanwhile, RCA worked with General Electric (GE) to develop its own version of the tabletop radio, the AR812, which it brought to

market in March 1924. Armstrong and his coworker, Harry Houck, were the principle contributors to the AR812, the first RCA superheterodyne, which utilized the second harmonic principle in its circuit.

RCA RADIOLA II PORTABLE RADIO, 1923RCA, along with other manufacturers, sought to simplify and reduce the sheer bulk of the radios offered, so as to develop a broader market appeal and to merchandise the sets for broader public consumption. RCA announced its Radiola II in December, 1922. Yet, the Radiola II was not sold until late January 1923, or nationally advertised until June 1923, due to a shortage of the required UV199 radio tubes and other issues, including RCA’s desire not to encroach on the sales of remaining inventory from its prior models.

Manufactured by GE for RCA, the Radiola II (AR800) was RCA’s first truly portable radio. However, although it was produced in an attractive mahogany cabinet, it still had no amplifier, speaker or antenna. The total production run was 9,594, and the retail price was advertised at $97.50 (equivalent to $2,014 today). The purchase included a pair of Brandes headsets, two UV199 tubes and a set of batteries. The customer only needed an antenna to tune the stations. The radio used a tuned radio frequency (TRF) receiver with a reaction (regenerative) circuit, with one audio frequency stage requiring a set of dry batteries: 2 x 22.5 volts and 2 x 4.5 volts. One of the promotions stated: “With even with an improvised antenna it will pick good, big distances-clearly. And over short distances, it will operate a loudspeaker.”

DEVELOPMENTS 1923-1924In February 1923, just one month after Goldsmith had seen WE’s seven-tube superheterodyne, the tabletop

Model 4A radio, Armstrong walked into David Sarnoff’s office at RCA with his own simplified model. By using WD11 tubes and combining functions, he had whittled his model down to a (just barely) portable suitcase. Sarnoff, RCA’s legendary president, immediately saw the possibilities.

Armstrong was a flamboyant personality. In 1923, he climbed the WJZ (now WABC) antenna located atop a 20-story building in New York City, where he reportedly

did a handstand. He answered a witness who asked him why he did “these damn fool things” by stating, “I do it because the spirit moves me.” Armstrong had prearranged for photographs to be taken, which he had delivered to Sarnoff’s secretary, Marion MacInnis. Armstrong and MacInnis married later that year. Armstrong bought a Hispano-Suiza motor car before the wedding, which he kept until his death. RCA seized on the moment to produce publicity photos of Armstrong presenting Marion with the world’s first portable superheterodyne radio as a wedding gift.

RCA’s engineers recognized that commercial production could be feasible. Sarnoff saw a chance to scoop the market and cancelled millions of dollars in existing production orders with Westinghouse and GE to prioritize the new project. RCA’s top engineers (many familiar to the Radio Club of America) including Armstrong, Alfred Goldsmith, Harry Houck, Albert Hull and Irving Langmuir worked to solve problems with tubes,

oscillator circuit feedback, compact circuit designs and packaging everything into a smaller case. Since the superheterodyne was the first decent commercial radio on the market, RCA understood that the next imperative was to develop and market a truly self-contained version.

RCA’s entrants into the burgeoning portable radio market were made by two of its suppliers under cross-licensing agreements: one made by Westinghouse and another by GE, both shareholders of RCA since its inception

in 1919. Generally, RCA’s radios manufactured by the two different companies sometimes left those two manufacturers occasionally competing with each other for the same consumer niche. GE’s portable radio, the Radiola 24, was contained in a converted leather-covered suitcase that loosely resembled Armstrong’s initial concept. Westinghouse’s portable radio, the Radiola 26, was a completely new set that looked and truly represented a brand new concept for portability. It provided everything—the antenna, circuit, and sound reproduction—in a small custom-designed wooden case.

RCA introduced the first mass-produced superheterodyne radio in 1925, only after both its tabletop AR812 models and its console Super VIII models completed their production; both would remain available through stores into 1926.

RCA RADIOLA 24The Radiola 24 was manufactured by GE and introduced in May 1925 at a suggested retail price of $195 (less batteries). The Radiola 24 was mostly a repackaging of earlier components into a salesman sample-sized suitcase that opened. The antenna was removed from

the lid and then inserted into the top of the radio. Superheterodynes generally still were expensive, but the portability offered a new consumer product, even if it was not glamorous. The Radiola 24 was basically a six-tube Radiola AR812 in a smaller package, enclosed in a cowhide leather case, which included a large folded horn speaker in the main case and an antenna that could be plugged into the top of the set after removing it from the lid. The comparable cost of a new Ford car was $299. The Radiola 24 was dropped from RCA’s lineup by Christmas 1925.

RCA RADIOLA 26, 1925

The Radiola 26 had its roots in research conducted by Arthur Van Dyck. Formerly an engineer for Marconi Wireless Telegraph Company of America, Van Dyck joined GE in 1919 and moved to RCA in 1922. One of his projects sought to design a portable superheterodyne. Some of his early work eventually evolved into the Radiola 26 after Armstrong’s and Houck’s new circuit concepts were incorporated.

The Radiola 26 was manufactured by Westinghouse for RCA and introduced in June 1925 at a suggested retail

price of $225. The simple but finished walnut box with disappearing brass latches and copper controls formed a bridge between current tabletop radio designs and a new portable concept. The new integrated design resembled the AR812 circuit and contained six tubes, batteries, rotating loop antenna, and a folded horn speaker. Instead of metal, it had a decorative wood grill over the horn. It was fitted with a more restrained antenna built into the front door that could rotate, and whose wiring was hidden in channels drilled into the case and soldered to the door hinges. Additional wiring was channeled into the frame of the door, which had a rotating contact point at the base of the antenna door.

The radio even came with a “docking station” that held larger batteries if used in stationary mode (the battery box/docking station can be seen in the picture). The docking station also could be connected to an outside antenna for better reception. (The docking station had a coil that couples to the door/loop antenna when it is fastened to the back of this radio, and also had a trimmer capacitor that matched the outside antenna to the radio.) Westinghouse integrated a brass horn speaker that folded in on itself to replicate the effectiveness of a 31-inch horn, but a separate speaker could be used instead to improve audio quality. Aluminum, used under the walnut, reduced the weight. The antenna even could be dismounted from the door hinge and remounted on the back of the radio. Electrical connections on the rear provide connectivity for the antenna. Thus, although it was portable, this radio still could be used as a tabletop model for the living room.

SUCCESSBy 1925 the portable radio had come of age. Hugo Gernsback’s Radio News published its “First Annual Portable Radio Set Directory” listing 22 models from 16 manufacturers. RCA’s Radiola 26 used the same six-tube superheterodyne/reflex design that Edwin Armstrong perfected for RCA in 1924 (in doing so he became the largest single owner of RCA stock). The walnut Radiola 26 blew away the leather-suitcase Radiola 24 and its competitors. Approximately 20,000 Radiola 26 radios were made compared with only 8,000 Radiola 24s; many Radiola 26s have survived to today, so that radio seems to have been preserved by the general public.

Armstrong, Houck, Goldsmith, Hull, Langmuir, Van Dyck and Sarnoff—these are all legendary names that should be familiar to Radio Club of America members. They created the legacies we now share today. As we carry our cellular phones in our pockets for use as minicomputers and digital radios in an Internet age, we should reflect back and remember that the simplest reception of radio signals once required leading-edge commercial equipment that occupied a tabletop, then a suitcase, and then the first portable radios.

So you just passed your ham radio exam and you are officially “on the air” – now what?

If you are like many newbies to the art of amateur radio, just being able to make contacts (QSOs) using that brand new call sign, and exchanging information with others in faraway lands using your own equipment from your garage or backroom “radio shack” is exciting. I remember my first QSO was with another enthusiast who was using a portable radio, on a 220 MHz linked repeater network, who was watching the sunset from the summit of Half Dome in Yosemite National Park. He took the time to not only confirm my first contact and welcome me to the world of amateur radio, but also proceeded to describe the breathtaking views of the valley below and the multitude of colors as the sun fell below the horizon. This, all while sitting in my garage some 400 miles away! Upon reflection, this was probably just another one of your typical “ragchews” (casual conversations); to me (keeping in mind that I was a youth at the time) it was one of those lifetime milestones that just had to be shared with others over and over and over … yeah, you’re right, I was probably the only one truly excited about it.

Of course, there were more interesting events to come, like working Nets and the occasional DXing Contests, participating in Ham Radio Field Day, or attending what many consider the ultimate experience for hams; the Amateur Radio Hamfest.

As the members of the prestigious Radio Club of America (RCA) well know, the club is highly dedicated to encouraging the youth of America to become interested and involved in this world of amateur radio, and to embrace the technology, learn the theory, and practice the discipline that goes hand in hand with it. And while this is often seen by the outside observer as merely a “hobby,” in reality the expertise gained also can be used to assist public safety in providing lifesaving services to the communities in which they live. When we talk to the youth about Amateur Radio, and the fun of events and contacts, we also should emphasize that they also could become a part of the greater public safety community. Many of the radio technicians and communications personnel working in public safety today started out as a licensed amateur radio operator as a youth and later became involved in supporting their local public safety agencies through such organizations as the Radio

Amateur Civil Emergency Service (RACES), or the Amateur Radio Emergency Service (ARES).

But did you know that as a licensed radio amateur, your expertise is also an integral part of the U.S. Department of Homeland Security’s (DHS) Office of Emergency Communications (OEC) National Emergency Communications Plan? Known as AUXCOMMs (Auxiliary Communications personnel), amateur radio operators have been assisting public safety for more than the last 100 years with critical communications during natural and manmade disasters. Amateur operators are a huge asset because they utilize systems that are totally separate from those used by public safety, and the general public; they often can send and receive messages over great distances when normal communication systems over large areas are down. AUXCOMMs provide various types of communications support to emergency management, public safety, and governmental agencies, not only during emergency incidents, also for planned events, community functions, and training exercises. Trained AUXCOMMs are a valuable communications resource that can be used by local, county, regional, tribal or state agencies and organizations. The OEC’s Auxiliary Communications Field Operations Guide (AUXFOG) is a great source of information and can be found on the DHS website at www.publicsafetytools.info. This page contains additional links to “TA/SCIP Requests” that provide a catalog of courses, descriptions, and details on how to take an AUXCOMM class under the Communications Unit Training and Support section.

Requirements to take the AUXCOMM training class include completion of the Incident Command System (ICS) modules IS-100, IS-200, IS-700, and IS-800, all of which are available to take online at www.fema.gov and at no cost. You must hold a General Class FCC License or above (yep – If you are a Technician Class you will need to study and get that General ticket), and have some previous experience in providing auxiliary communications (e.g., RACES, ARES).

No matter if you are just learning about amateur radio through the RCA Youth Program or have been an amateur radio operator for decades, you should consider volunteering with one of your local public safety services. Who knows, it could lead to a whole new career.

SIGNAL magazine marked its 70th anniversary in 2016. This is the primary

publication of The Armed Forces Communications and Electronics Association (AFCEA), which was established in 1946. AFCEA is a non-profit membership-driven association serving the military, government, industry, and academia as an ethical forum for advancing professional knowledge and relationships in the fields of communications, information technology, intelligence, and security. AFCEA traces its roots back to the Civil War but realized its modern organizational form in 1946. It has more than 35,000 members in 151 chapters, and 1,590 corporate members. AFCEA helps members advance information technology, communications and electronics capabilities.

As part of its anniversary, SIGNAL published a series of essays based on interviews with members and leaders in the field. These essays offer an interesting perspective on the shifting priorities and demand for communications and information technologies, and the adoption and application of those technologies over the last seven decades. Changing circumstances and advances in technology produced evolving command structures, shifting requirements for

information flow, differing security concerns, and adaptations in the management of independent units in the field, all developed with rapidly changing solutions and approaches.

The essays also note the interplay of battlefield needs, available advances in current technology, and the military’s demand for new solutions which, in turn, stimulated the development of even more new products and concepts. Leadership and evolution came from contributions made by the commercial civilian world, the military-industrial complex, and purely military arenas.

The series is available at http://www.afcea.org/content/?q=table-contents-september-2016 and the archival links to the previous issues at http://www.afcea.org/content/?q=archives. A summary of the 2016 series follows:

The rise of China and Chinese technology research and industry has been an ongoing

source of headlines and debate (or lack thereof) among American policymakers. However, the Institute of Physics issued a special report about the state of Chinese Physics in the September 2016 edition of Physics World.

Plans to build a 240 GeV Circular Electron–Positron Collider (CEPC) that would outperform CERN’s Large Hadron Collider are just the latest example of a massive buildup of investment by the Chinese. The Five-hundred-meter Aperture Spherical Telescope (FAST) is now operational, while the China Spallation Neutron Source in Dongguan is due to open next year. In addition, the China Jinping Underground Laboratory has plans to study neutrinos, dark matter and stellar reactions, and the country’s space program will launch its first lunar sample-return

mission next year and land the world’s first craft on the far side of the moon in 2018. Meanwhile, the China Institute of Atomic Energy is working on an ambitious “fast” reactor program, which seeks to build a new generation of nuclear plants that reuse waste as fuel. An experimental fast reactor opened in 2011, with a demonstration plant set to be built by 2023 and a commercial facility by 2030. And, in August, China launched the world's first satellite dedicated to testing the fundamentals of quantum communication in space.

China has realized that research should not just meet short-term goals, such as developing high-speed trains, solar panels or new drugs. “Blue-skies” research that can yield long-term dividends has been, and is becoming, a major national initiative. Spending on R&D as a fraction of gross domestic product (GDP) has more than doubled since 2000 to 2.1% in

2014 according to the Organization for Economic Co-operation and Development (OECD). The budget of the National Natural Science Foundation of China (NSFC) has risen 300 percent over the past 30 years, with most of that rise occurring in the last decade. Elsevier’s Scopus database reports that Chinese researchers accounted for almost 19% of all scientific and research papers published in 2015. And in June, China’s president, Xi Jinping, told a meeting of Chinese scientific leaders that the country should be a leading scientific innovator by 2030 and a dominant scientific country by 2049.

This dramatic growth in basic research will have major implications for American science, technology and industrial development. The special issue of Physics World is available at http://tinyurl.com/z6crswg.

China launched the world's first quantum science satellite on August 16, 2016. The

satellite is dedicated to testing the fundamentals of quantum communication in space. The collaborative endeavor between the Chinese Academy of Sciences and the Austrian Academy of Sciences began in 2011 and the assembly was completed earlier this year. The 600 kilogram (kg) satellite is now in Earth orbit at 500 kilometers (km) above ground.

The craft's main instrument is a "Sagnac" interferometer that is used to generate two entangled infrared photons by shining an ultraviolet laser on a non-linear

optical crystal. The $100 million Quantum Experiments at Space Scale (QUESS) mission will demonstrate the feasibility of quantum communication between Earth and space, and test quantum entanglement over unprecedented distances. The main goal of QUESS will be to demonstrate quantum key distribution (QKD) between the satellite and two stations on the ground – the Nanshan 25 meter (m) telescope at the Xinjiang Astronomical Observatory in western China and the Xinglong Observatory in Yanshan, 200 km south of Beijing.

Once these targets have been met, the Chinese team then

will collaborate with Anton Zeilinger and colleagues at the University of Vienna to create an "intercontinental" QKD channel between Beijing and Vienna, with the option of including stations in Italy and Germany.

"QUESS will be the first test of quantum communication with a satellite," says Zeilinger. "It can also be seen as a very significant step towards a future worldwide quantum Internet."

Indeed, China is planning to launch several similar satellites to create a quantum communications network by 2030. Additional information is available at http://tinyurl.com/jcp7otn.

The IEEE Communications Society (COMSOC) has issued a white paper “Protecting

the Sky: Signal Monitoring of Radio Controlled Civilian Unmanned Aerial Vehicles and Possible Countermeasures.” This whitepaper provides insights into the use, specifications, and impact of radio-controlled (RC) unmanned aerial vehicles (commonly referred

to as "drones"). UAVs intended for recreational use increasingly are being used for other (sometimes hostile) purposes. These include: observing/disturbing public events; spying in protected areas; smuggling contraband into prisons; endangering/threatening commercial air traffic; and entering restricted airspace. A technical approach for countering the threats

posed by such drones is described, and includes: monitoring the spectrum for relevant signals; identification of frequency-agile RC signals; direction finding; and possible defensive countermeasures. The whitepaper can be downloaded at http://tinyurl.com/h4pv5ur.

Bell Labs, the IEEE, and the IEEE Information Theory Society unveiled an IEEE

Milestone in Electrical Engineering and Computing recognizing Claude Shannon on April 30, 2016. The milestone was placed as part of the Claude Shannon Centennial Conference held in Murray Hill, N.J. The plaque reads:

“The mathematical principles of Information Theory, laid down by Claude Elwood Shannon during the period 1939-1967, set in motion a revolution in communication systems

engineering. They quantified the concept of information, established fundamental limits for the representation and reliable transmission of information, and revealed the architecture of systems for approaching them. Today, Information Theory, continues to provide the foundation for advances in information collection, storage, distribution, and processing.”

Shannon was an electrical engineer, and cryptographer widely known as "the father of information theory." He is noted for his landmark paper published in 1948. He is

perhaps equally well known for founding digital circuit design theory in 1937 while he was a 21-year-old master's degree student at the Massachusetts Institute of Technology (MIT). He wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical, numerical relationship. Shannon contributed to the field of cryptanalysis for national defense during World War II, which included his basic work on code breaking and secure telecommunications.

In 2015, Harish Krishnaswamy, an electrical engineer at Columbia University, demonstrated the

ability to transmit and receive signals on the same frequency using two antennas in a full duplex radio that he built. In April 2016, Negar Reiskarimian, a Ph.D. student under Krishnaswamy, embedded this technology on a chip that eventually could be used in smartphones and tablets. In Negar’s chip, the transmitter and receiver share a single antenna.

Typically, smartphones and tablets exchange signals over at least two antennas, where the signals are coordinated either by time or frequency. In time-division duplex, the transmitter and receiver take turns broadcasting on the same frequency. In frequency-division duplex, the transmitter and receiver broadcast on separate frequencies at the same time.

Harish’s research and his new chip circumvent “Lorentz Reciprocity,” where electromagnetic waves are thought to move along the same paths when traveling both backward and forward. Historically, Lorentz Reciprocity has enabled engineers to bypass reciprocity by designing circulators built of magnetic materials that disrupt the reciprocity by permitting waves to flow only forward and not backward, which allows for the simultaneous transmission of two signals. This type of circulator is expensive and bulky for smartphones, and the magnetic fields disrupt other

functions. Consequently, this type of circulator most often is used for military purposes.

Negar overcame the reciprocity issue by implanting silicon transistors onto the face of a CMOS chip in an arrangement that reroutes signals as they are captured by both the transmitter and the receiver, in order to avoid interference. The signals then circulate in a clockwise fashion. Performance is further enhanced by using an echo-cancelling receiver that the lab also pioneered, which prevents the transmitted signals from echoing back into a receiver when a full duplex radio is in operation.

Additional research is needed to increase the power levels that are necessary to connect to a mobile network.

EDITOR’S NOTE: This issue of the Proceedings of the Radio Club of America brings another installment from the next generation of inventors and developers in wireless and radio. The Voices of Tomorrow column provides a place for younger people to share their work in a professional setting. RCA is interested in finding students (primarily college or high-school level) who are interested in writing about their explorations, ideas and contributions to the fields of wireless and radio. We congratulate Divyam Mishra on his first professional publication, and we encourage submissions by others for future columns. Please contact the Editor, David Bart at [email protected], for further information or to submit draft articles for publication.

In the era of technological advancement, we often are reactive in dealing with maintenance problems. Frequently, on short notice, we are drawn forcefully

toward fixing the problems that suddenly become priorities. Can technology turn us from reactive to proactive by predicting when certain gadgets may malfunction, and allow us to do preventive maintenance?

The solution lies in predictive analysis of data-in-motion, i.e., recently generated data that is not stored yet. These analytics produce results to alert us about impending problems. The solution must have a set of known rules or patterns it can apply on data-in-motion to generate rapid alerts.

A network of sensors can intelligently collect data-in-motion from things around us, and run predictive analytics to give us meaningful information about possible failures. This provides us a way to learn about failures before they happen, and gives us an opportunity to proactively fix them rather than reactively responding to them after they occur.

OVERVIEWI have undertaken an engineering project that combines the concepts of data-in-motion, predictive analytics, and Internet of Things (IoT) technology. The product I am developing contains Arduinos with temperature sensors attached to them that communicate via wireless protocol to a centralized Raspberry Pi in the home.

Once the Pi is placed in the home, the main device will interact with all of the sensors, and then the sensors will pair to the Pi. Each sensor in the Pi’s main program will have its own identity attributes, so that specific data can be sent to the cloud in an organized manner. The centralized Raspberry Pi will evaluate the data and store it in the cloud, from where the owner can retrieve data on his/her device.

This system also will be able to analyze temperature patterns by using a temperature and humidity sensor to collect data that will be processed by the Raspberry Pi. The system will document this data in the cloud by storing the data and then displaying this data with graphs and analytics. The data can be displayed via Augmented Reality.

In the future, this type of system, which collects volumes of data, not only will be present in your home, but also will be present in our cars, offices, appliances, and healthcare. Figure 1 shows all of the potential uses of this system. This system will be able to detect problems that might occur in the future beforehand, so that we can be more reactive.

IMPLEMENTATIONThe Home Sensor Network is built by placing Arduinos around a house. The Arduinos collect temperature data and transmit to the centralized Raspberry Pi. A user can

receive temperature data via email. The Raspberry Pi then uses a Passive Infrared (PIR) sensor and camera to detect movement in the house.

When the PIR sensor detects movement, it triggers the camera to take multiple pictures that are compared. If a difference is spotted, the pictures are uploaded to Dropbox. Figure 2 shows the design of the system.

CHALLENGESOne of the challenges of this project was to detect movement. The PIR sensor is not reliable due to its sensitivity to small variations. For example, if local heat is present, the PIR sensor will sense the heat instead of movement. The solution is to have the camera module double check the PIR sensor’s alarms. We do this by capturing multiple images when the PIR sensor detects something. Figure 3 shows my work environment and the prototype. These images are then compared side by side for pixel differences of more than 10 percent. Thus, the PIR sensor and camera module work together to create better reliability and security.

Another major design issue that needed to be resolved related to the structure of the program that runs on the Raspberry Pi. A centralized program on the Raspberry Pi processes data from the sensors. In this process, the camera module becomes a bottleneck and introduces delay in the system. Figure 4 shows pseudocode that provided the solution. The time needs to be shorter

because it takes too much time to boot up the camera, take a picture, and send it to the cloud.

To solve this problem, an asynchronous processing model is used to perform these steps in a distributed manner. The main program submits a job in the Pykka Actor queue to process camera operations asynchronously alongside the main program. Figure 5 shows a section of the code written in Python.

RESULTSAs the speed of the movement increased, the reliability of alerts decreased. Using a higher-resolution camera slows down the system performance, while a lower-resolution camera gives optimum system performance at the cost of reliability. Figure 6 visually shows the reliability of the system in particular situations.

Cloud storage is not yet reliable, and some uploads are guaranteed to fail. This creates a problem as data and alerts could be lost. Cloud storage service is also inconsistent – meaning that data updates are delayed, and some users may see stale data from different parts of the world. Figure 7 illustrates the reliability aspects of cloud storage.

APPLICATIONBy looking at the results, it is apparent that reliability must be improved. The project in its current form only tests a single Arduino with a Raspberry Pi. It is vital to determine how well this system can scale after adding multiple Arduinos to the design.

My results suggest that the reliability of this system can be improved greatly, especially in the movement-detection system. Further research is needed to develop a fully operational prototype. This project has not yet addressed the need for securing the data all the way from data generation at sensors to data-in-motion between the Arduino, the Raspberry Pi, and the cloud storage. Figure 8 shows where the data will need to be secured.

FUTURE STUDIESApart from increasing reliability, scalability, and security, the next logical step is to create a Web-based analytics engine that can analyze data from the cloud storage and provide alerts to users via augmented reality.

In this setup, a RESTful Web Service (REST is an acronym for Representational State Transfer) will allow a mobile application to retrieve data from the analytics engine and to display alerts and data via augmented reality. Figure 9 presents my concept for the fully implemented system.

EDITOR’S NOTE: This issue of the Proceedings of the Radio Club of America brings another contribution from the next generation of inventors and developers in wireless and radio. The Voices of Tomorrow column provides a place for younger people to share their work in a professional setting. RCA is interested in finding students (primarily college or high school level) who are interested in writing about their explorations, ideas and contributions to the fields of wireless and radio. We congratulate Austin Schaller on his first professional publication, and we encourage submissions by others for future columns. Please contact the Editor, David Bart at [email protected], for further information or to submit draft articles for publication.

Wireless transmission has developed significantly since its introduction in the late 19th century. With the advent of semiconductors, radio

frequency integrated circuits (RFICs) continue to consume less power, offer more functionality at the same cost, and now consist of entire radio systems on a wafer only a few square millimeters in area. The modern software-defined radio (SDR), a device that controls physical layers of the radio via software, has become a practical learning platform for radio enthusiasts around the world. Their unique ability to be configured without physical adjustment allows SDRs to be used extensively in the military, radio astronomy, and more recently, the Internet of Things (IoT). Today, numerous open-source and commercial SDRs are available; however, designing a software-defined radio from scratch offers a wealth of other development and learning opportunities that often involve multiple engineering disciplines. This article describes the process of designing an SDR from start to finish.

BASIC TRANSCEIVER ARCHITECTURE A functional – indeed, even cognitive – SDR is made possible by a combination of RF, analog, and digital theory. Before applying the theory, a first step is to choose the desired radio architecture. Rather than design a heterodyne, homodyne, or low intermediate frequency (low-IF) system from the ground up, for example, an RFIC-based solution is recommended, which will allow designers to focus on customizing the external RF front-end. Frequency synthesizers, mixers, and other RF components that are common in complex radio architectures are instead embedded on a packaged substrate – greatly simplifying the design process and often improving RF performance. A sample design for an RFIC-based SDR is shown in Figure 1, comprised of the RF front-end, analog, and digital subsystems. All three subsystems may be modified and extended. Several examples may include the addition of a variable attenuator to limit received or transmitted signal power, or perhaps a coupler and RF detector to measure forward and reflected power.

Digital peripherals communicate with the microcontroller unit (MCU) through an interface such as I²C or SPI. The component datasheet will specify which interface it requires. Note that, in this particular instance, an external microcontroller unit communicates with the transceiver IC in order to control, send, or extract information. This is not always the case, as many wireless ICs exist that combine both the microcontroller and transceiver into one package.

COMPONENTS AND SIMULATIONPart identification, though sometimes arduous, is a critical aspect of the design process and often

can depend on the underlying project goals. If the intended application is narrowband and does not require a fast data rate, most mid-range RFICs will suffice. Alternatively, if a wideband SDR is of interest, the characterization of components across the entire frequency range will be important to identify. In any case, a good rule of thumb is to balance performance and cost – two aspects that RF engineers must contend with in real life. This implies a basic understanding of the theory, or at least the basic concepts, is grasped to determine the appropriate issues and questions that will need to be addressed. What loss do signals experience from the antenna to the low-noise amplifier? How should the circuit board layers be organized to optimize RF performance? To help with answering these types of questions, datasheets, textbooks, or individual experiments are helpful. In addition, open-source software, at no cost to the designer, is available to simulate system behavior. Figure 2, for example, depicts the Scattering-parameters (S-parameters) of a pi filter using Quite Universal Circuit Simulator (Qucs) software. Such a circuit may be used to remove unwanted frequency components prior to reception or after transmission. Because voltages and currents are difficult to measure at higher frequencies, S-parameters are used to describe how RF signal power propagates through multi-port networks. Conveniently, touchstone files, which contain S-parameter measurements, can be downloaded from component manufacturers online and directly imported into Qucs. This enables a more realistic representation of component performance to be modeled. Simulation only can go so far. Sometimes a faster and more informative measure could be obtained from a prototype and test components before integrating them into the final design. Creating a prototype board for a power amplifier, for example, would assist with understanding how to filter amplifier harmonics.

SCHEMATIC ENTRY AND PCB LAYOUTAfter component identification and simulation, and even the formulation of a bill of materials, schematic entry and printed circuit board (PCB) layout follows. Designers have numerous options at their disposal, including open-source programs such as KiCad or DesignSpark

PCB. Selecting one or the other depends largely on personal preference, and thus, users are encouraged to explore multiple options before applying extensive effort. Schematic entry is generally a straightforward process: if the symbol for a particular part does not exist, the user must create it and save it to a specific library. Integrated circuits, such as the RFIC or power amplifier generally fall into this category for the reason that such programs cannot possibly contain every conceivable part. After creating a schematic symbol for a given part, a PCB footprint is made by referencing the datasheet and following the ascribed dimensions.

Circuit board layers, in addition to the placement of components, can have a significant influence on RF performance. Unless designers have prior experience creating RF circuit boards, avoiding a two-layer design is recommended. A four-layer board, utilizing the first layer for RF, the second layer for ground, the third layer for power, and the fourth layer for signals will exhibit better performance by reducing spurious emission and increasing transmission line efficiency. The latter improvement is made possible by combining the first and second layer, creating a type of transmission line known as a coplanar waveguide with ground. The dimensions of the transmission line, such as trace width or trace-to-ground spacing, can be determined using calculators online or ones that are included with PCB software (e.g., KiCad). In addition to using four layers and transmission lines for interconnecting RF components, designers also should avoid placing any digital circuitry opposite the receiver. Developing a complete understanding for the function of each component, and their influence on components within close proximity, will help to inform the layout process.

DT9 SOFTWARE-DEFINED RADIOTo demonstrate the feasibility of designing a digital transceiver from scratch, a 902-928 MHz ISM band software-defined radio, known as the DT9, is presented. The design strongly resembles the block diagram shown in Figure 1; however, a few subtle differences do exist. A wireless MCU is used, which combines both the microcontroller and transceiver into one, and a third RF path was added to bypass the low-noise amplifier (LNA) in the event of receiving strong signals (i.e. to avoid

receiver saturation). Two couplers were placed towards the output and routed to a detector as a way to measure forward and reflected power. This allows the SDR to gauge whether or not all the power from the power amplifier (PA) is successfully radiated by the antenna. If that is not the case, the SDR can cease transmission and inform the user.

The DT9 supports data rates up to 4 Mbps and several modulations, including multilevel Frequency-Shift Keying (FSK), Minimum-Shift Keying (MSK), and On-Off Keying (OOK). Output power, which can be adjusted automatically by the SDR to increase power efficiency, extends from 0 to +30 dBm (1 mW to 1,000 mW). Two interfaces exist that allow users to send and extract information from the DT9, namely RS232 and SPI. At a mere 5.5 mA receive current and 13 mA transmit current at +10 dBm, the DT9 is ideal for applications that require low power. All of this functionality is constrained within a 1 by 1.7-inch square area.

As demonstrated by the flexibility of the DT9 hardware, numerous learning opportunities exist. While former knowledge of electronic circuits and RF is useful, it is not completely necessary. Even with a basic understanding of transceiver architecture, individuals who have an interest in designing their own digital radio can proceed in the right direction and research details along the way. Datasheets, textbooks, or individual experiments can serve as a way to discern upcoming steps. After completing the hardware, designers also can explore additional learning opportunities via firmware and software.

EDITOR’S NOTE: The Radio Club of America long has maintained a strong presence at the annual Dayton HamVention. This year brought even more participation by RCA, and we registered a record number of new members. RCA’s Carole Perry continues to provide one of the key programs at Dayton: the annual, and legendary, educational event of the year, the Dayton Youth Forum. With the permission of CQ Magazine, RCA has reprinted a detailed account written by Carole describing her experiences at the 29th Dayton Youth Forum.

By all accounts, this year’s Dayton HamVention® Youth Forum (Photo A) had all the ingredients for a highly informative, successful—and 29th annual—

showcasing of our young hams. Except for the fact that we had standing room only (Photo B), and actually ran out of pre-printed prize tickets, it was a wonderful experience for our young presenters.

DENVER BEFORE DAYTON…Before telling you about Dayton, though, I’d like to go back in time by one weekend, when I had the honor of conducting the Youth Forum at HamCon Colorado outside Denver with two experienced RCA Young Achievers and two new hams; all of whom were fairly local to the convention. I always like to showcase local youngsters at the regional forums I do across the country so that everyone becomes aware of their local young talent.

Divyam Mishra, KD0OOE, age 16, is an RCA Young Achiever who has been at several forums with me, including the Dayton Youth Forum two years ago. He spoke about the research he is doing at the University of Colorado at Boulder. Austin Schaller, KD0FAA, is 21 and is an electrical engineering student at Le Tourneau University. Austin, too, has been a presenter at many forums with me discussing his research on fractal antennas. These are two incredibly talented young hams.

Nickolas Foss, KE0FGI, is 13 years old. He gave a fabulous talk about the opportunities he has had exploring ham radio as a new ham. Cheyenne Sterner, N0CKS, is in the 8th grade and is already a member of at least three local ham radio organizations including Arapahoe County ARES. All four of these youngsters

were excellent presenters and I was honored to moderate the Youth Forum.

Everyone involved with the HamConColorado convention and the ARRL Rocky Mountain Division could not have been more welcoming and accommodating. It was a total pleasure to have been invited to this special event!

DESCENT TO DAYTONDescending from HamCon Colorado’s 12,000 foot elevation and catching a flight two days later to Dayton was “interesting.” Attending Dayton is like coming home for me. The warmth and helpfulness afforded our HamVention Youth Forum is superb! For the past 10 months, I have been interviewing the 11 young hams who ended up being our presenters for the 29th Youth Forum. One more youngster who won the “Young Ham Lends a Hand” contest was recognized as well. His name is Sean Flynn, KD2BFI, and he is 16 years old. Besides promoting ham radio through his 4H STEM presentations, he has logged in over 100 hours in community service events in the past three years. If you know of a young ham who behaves in the spirit of service to his or her community, be sure to send me information about them so they can be considered for next year’s forum.

Before the first youngster took the podium, I thanked Maria Lysandrou, KB9BUS, who spoke at Friday’s Instructors’ Forum on the topic of “Attracting Females

into Ham Radio.” This 17 year old gave excellent suggestions for the high school and higher, recruitment of females into our hobby and service. I’d also like to acknowledge the great work of Lukas Purasson, KD2ISB, and Nick Roschewsk, KD2HBR, two high schoolers who spoke about “Antenna and the Engineering Design Competition” at my Instructors’ Forum, as part of Bob Roschewsk, KA2PBT’s, presentation about amateur radio in high school.

Brandon Giek, WA9REV, age 16 (Photo C), was first to the podium. He spoke about an ARISS (Amateur Radio on the International Space Station) contact he was involved in and his title was “Cell Phones Down, Radios Up.” He played a video clip of some of the students from Maconquah School asking questions of astronaut

Photo C: Sixteen-year-old Brandon Giek, WA9REV, was the Youth Forum’s first speaker. His presentation, on a contact with the International Space Station, was titled “Cell Phones Down, Radios Up.”

Photo D: William Ferguson, KJ4EYZ, shared tips on setting up your station for successful DXing. How would he know? Well, he was licensed at age 7 and earned his DXCC at age 8!

Kimiuya Yui, KG5BPH, on board the ISS on August 27, 2015. The astronaut spoke of how he was never bored from the views they observed, and also about how someone gets qualified to be an astronaut.

Eli Musgrave, KM4HFZ, age 15, and Zach Haidari, KM4QIV, from the Mill Springs Academy in Alpharetta, Georgia spoke wonderfully about “Discovering the Fun and Magic of Digital Radio Communications.” They showed us some of the activities they participate in at their school club, such as Field Day and the School Club Roundup. Their teacher Martha Muir, W4MSA, was right there, rooting them on.

Skyler Fennell, KD0WHB, age 17, spoke about “Home Brewing on a Budget.” At the HamCon Colorado banquet the previous weekend, Skyler was called up to receive the ARRL Rocky Division 2015 Young Ham of the Year award. He was then called back to the podium to receive the group’s Technical Achievement award. He spoke about his interest in electronics and how it led him into ham radio. He showed slides of all the repeater projects he’s been involved with including the STEM school 440MHz repeater and others using home brew methods and equipment. Paul, N0AH, and Anna Veal, W0ANT, worked with him on the school projects.

William Ferguson, KJ4EYZ, age 14 (Photo D), spoke about “Setting Up a Radio Station to chase DX.” William was the 2015 Youth Plaque winner for the 2015 Virginia QSO Party sponsored by K4AMG. He was first licensed at age 7 and is one of the youngest in the world to receive his DXCC at the age of 8. He spoke about his increased capabilities of acquiring a DX station by using advanced DX chasing techniques.

Hope Lea, KM4IPF, age 9, spoke about “Talking through the Birds.” We saw slides of her satellite station and she spoke about getting ready for a satellite pass, and actually working a satellite. Her presentation culminated with a short video of her actually working a satellite and telling us she’d like to work more DX in the future.

Kelsey Seymour, K3LSY, age 17, spoke about “Preparing Yourself: an in-depth look at Go-Kits for Emergencies.” This young ham has been in scouting for 10 years, and acted as our IT person for setting up all the presentations on the laptop for our young presenters. As part of an Eagle Scout project he put together an “amateur radio to-go kit.” Besides outlining all the ham gear to prepare, he listed all the personal items to bring along to be self-sufficient for 24 hours. Some of the items listed were personal ID, cash, food, water, flash light, batteries and so on. Kelsey also suggested practicing using your go-kit during the year at such events as Field Day.

Jacob Nagel, AD0JA, a 16-year-old (Photo E) with a professional sounding speaking voice, was next. His topic was “CHIRP-It’s not just for the Birds: Using Computer Software to Program Your Radio.” To help minimize the frustration of new hams in programming their radios, Jacob took us through the use of CHIRP with radio programming basics including exporting listings from Repeaterbook.com.

Marty Sullaway, KC1CWF, age 14, spoke about “Homebrewing Fun and Contesting.” He explained why homebrewing is the way to go, for him. He listed cost, customizing your needs, and fun, as the main reasons he enjoys building his own equipment. His project, which he described in detail, was “antenna switching.” I had the opportunity of observing Marty on the radio while attending the August 2015 ARRL Boxboro convention. We can all be proud of the skill set he has achieved.

Photo E: Jacob Nagel, AD0JA, educated the audience on using CHIRP software to program mobile and handheld radios.

Dhruv Rebba, KC9ZJX, age 11 (Photo F) is in the 6th grade in Bloomington, Illinois. He enjoys dual citizenship with the U.S. and India. Thanks to the efforts of Michael Kalter, W8CI, in arranging for talented young hams from India to be part of our Youth Forum, young Dhruv was an excellent addition with his terrific presentation. He spoke about his “Inspirations and Accomplishments with Ham Radio.” Dhruv first attended HamVention in 2013 and got his initial inspiration there to get involved, learn more, and volunteer more. He has been helping communities in the United States and in India with radio communications. This accomplished young ham had to get cut off by me because of our time constraints, before he completed his entire presentation. Therefore, he is officially invited back next year to be the very first speaker at the 30th HamVention Youth Forum.

It was a delight for me to look out at the audience from the podium, and see the section that was reserved for the youngsters participating in the ARRL Youth Rally this year. Bob Inderbitzen, NQ1R, Marketing Manager of the ARRL spearheaded this year’s Youth Rally. Guiding the day long Youth Rally activities were ARRL Education and Technology Instructor Tommy Gober, N5DUX , and his wife Jennifer, KE5LNK. To quote from

the The ARRL Letter, “Tommy said the Youth Rally fed off energy generated during the earlier Youth Forum. The participants engaged in hands-on activities and ended with an HF operating experience.” Be sure to look for announcements of this great event at next year’s HamVention so you can pre-register your child to join the fun.

The incredibly generous sponsors of our Youth Forum are: RCA (Photo G), ICOM, MFJ, Kenwood, Kirmuss & Associates, L'Anse Creuse ARC, QCWA, Delaware Leheigh ARC, Heil Sound, W5YI, and ARRL. I am always grateful to efforts of my prize manager Ralph Irish, W8ROI, who gets all the gifts organized for us. All our young presenters left the forum with their arms laden with gifts. Other big prizes (Photo H) were given out to adults and to young people in the audience. ICOM generously donated an IC-7100 in addition to radios and other gifts it donated to my young speakers. We sincerely appreciate the support of all our sponsors!

Please send any creative ideas or suggestions you may have for our 30th HamVention Youth Forum next year, to [email protected]. Be sure to come and help us celebrate!

Photo G: The Radio Club of America is among the Youth Forum’s many long-running sponsors. RCA also sponsors its own “RCA Young Achievers” program.

Photo H: A table-full of prizes donated by various companies and clubs allowed every presenter and many audience members to head home with an armful of goodies.

Imagine a book that intertwines the early history of wireless with a crime mystery, and all of it true! In Thunderstruck, successful author Erik Larson

illuminates the life of Guglielmo Marconi, considered by many to be the father of long distance wireless. In the late 1800s, Heinrich Hertz, John Ambrose Fleming, Oliver Lodge, and many other scientists, were experimenting with “Hertzian waves” which appeared to travel invisibly across a table or room, yet no one could get beyond laboratory experiments and what appeared to be magicians’ tricks. Enter Marconi, born to an Italian farmer and an Irish woman from the Jameson whisky family, who without formal training or scientific education, is convinced that radio can be coaxed to go thousands of miles instead of a few feet.

Set in Edwardian London, the drama takes place on the stormy coasts of Cornwall, Cape Cod, and Nova Scotia. These were the days of spark gap transmitters, coherer detectors, and just a few years before the beginning of the Radio Club of America itself in 1909. (The title comes from the raucously loud noise that emanated from the spark gap transmitters in the “Marconi cabins” on board ships as the operators keyed in their Morse code [CW] signals.) Like other pioneers in wireless such as Armstrong, Marconi faced considerable opposition and outright hostility from his contemporaries, and patent battles, fighting off large competitors, and jamming of the airwaves were all a part of his story. Marconi was an early entrepreneur, long before the word came into common use, and exhibited an obsessive focus that helped overcome numerous obstacles but also made him rather distant socially.

But as if this were not enough for the reader, a parallel story enters the mix, of an unhappy medical doctor. I will not say more except that both stories are true, and they culminate in what was probably the most followed news event in the twentieth

century. The story leads us from Italy to the United Kingdom, to Massachusetts, Newfoundland, Nova Scotia, and Belgium. Along the way we are introduced to a host of interesting characters including a vengeful magician, a wannabe vaudeville singer, and even Winston Churchill.

Its 459 pages are organized in short chapters with many sections within a chapter, making it easy to put down and pick up multiple times. The author includes very detailed end references for every chapter, and an extensive bibliography which will help researchers and historians on either of the events portrayed. Enjoy this book as I did!
