The MFJ-4403 Transceiver VoltageConditioner provides reverse voltage, over-voltage, voltage transient and short circuitprotection. Gives super noise and ripple fil-tering and power supply buffering for yourbase, portable or mobile transceiver.

The MFJ-4403 really shines in mobile andportable operation where your non-idealvoltage source could cause extensive damage.

If you accidentally reverse your voltageconnection, the MFJ-4403 protects your

transceiver against instantdestruction and alerts you with abright warning LED. Once theDC polarity is corrected, the

MFJ-4403 recovers and operates normally. Heavy-duty transient suppressor handles

peak currents up to 200 Amps -- protects yourtransceiver from vehicle and poorly regu-lated power supply start-up voltage spikes.

MFJ brings high-end automotive audiotechnology to ham radio!

Four Farads of ultra high-value capaci-tors filters off virtually all power supplynoise and ripple, and provides enoughpower supply buffering so that even under-rated and marginal power supplies will runyour HF transceiver.

For temporary mobile operation -- rentalcar, weekend trips, vacations, etc. -- theultra high-value capacitors in the MFJ-4403 provide enough power supply buffer-

ing to let you run full 100 Watts SSB fromyour 10-15 Amp cigarette lighter socket.

Standard Anderson PowerpoleTM

connectors are used for the DC input andoutput. MFJ-4403 measures a compact4Wx3Hx2D inches.

MFJ Transceiver Voltage ConditionerProtects against -- Reverse Voltage . . . Over-Voltage . . . Voltage Transient . . .Short Circuits. Super noise and ripple filtering . . . Power supply buffering. . . Lets you run 100 Watt SSB from your vehicle cigarette lighter socket . . .

Today's compact100-watt HF transceiversare designed to oper-atefrom about 12-16 volts,

with output signal distortion, output powerproblems, and transceiver reset often occur-ring when voltage drops below 12 volts.

In the mobile environment, low voltageis caused in two ways: First - even lowresistance DC wiring can result in a notice-able voltage drop. For a 100-watt transceiverwith a 20-amp typical current requirement,just 1/10th of an ohm resistance in your DCcable and connectors results in a 2-volt drop!And second - when you turn your car off,the battery voltage drops from around 13.8volts to close to 12 volts after a short peri-od of time. Couple this with any voltagedrop in the cables, and you have a problem.

The MFJ-4416 Super Battery Boostereliminates low voltage problems by boost-ing input voltages as low as 9 volts up tothe desired 13.8 volts at up to 25 amps peakwith a typical efficiency of close to 90%.

It is compact at just 73/4Wx4Hx21/8D”and lightweight at 1.3 lbs. And the MFJ-4416 Super Battery Booster is designed to

be rugged, reliable, and easy touse.

MFJ-4416 includes AndersonPowerPoleTM connectors andhigh-current 5-way binding postsfor both the DC input and regu-lated output. An internal 30-ampinput fuse protects the unit fromexcess output current demands.

There are also selectable lim-its on the minimum voltage thatthe unit will accept: 9-volts, 10-volts (default), and 11-volts.

This protects you from over-discharging abattery and possibly damaging it. MFJ-4416also includes output over-voltage crow-barprotection should regulation be lost.

Two additional features offer ways toincrease efficiency even more! First, thereis an RF sampling port which can be con-nected to your transceiver's transmissionline with an MFJ-7733, $6.95 UHF-T con-nector. When this feature is enabled, theMFJ-4416 is bypassed unless RF is sensedso no regulator switching efficiency penal-ties are incurred during receive.

The second efficiency enhancement fea-ture is a user-adjustable output voltage con-trol which lets you set the output voltageanywhere between 12- and 13.8-volts.When setting the output at 12-volts, inputvoltages greater than 12V will passthrough, but the efficiency of the regulatoris higher. And lower input voltage meansyour transceiver will run cooler!

Typically save over 30 watts in heat dis-sipation during transmit, and even 3-4 wattsduring receive. So it can actually be goodto let the voltage sag to 12 volts, then let theMFJ-4116 protect you from lower voltages.

MFJ-4416 Super Battery BoosterKeeps your transceiver operating at full efficiency and performance by

eliminating low or marginal voltages in the mobile environment . . .

Based on extensive speechresearch, the MFJ-653 uses optimized fre-quency shaping to concentrate the energyin the band of frequencies where speechintelligibility is concentrated. It alsoremoves powerful low frequencies thatoverwhelms the important high frequenciesthat carry intelligibility.

You can boost the highly intelligible bandof frequencies centered around 2 kHz by upto 16 dB and gently remove the powerful, lowfrequencies that have little intelligence. Thehigh-pass filters cutoffs are 1.1 kHz and 500 Hz.

Using a SSM-2166 broadcast industryspeech compression IC the MFJ-653 syl-labic compressor with its adjustable 15 to 1compression ratio can nearly double your

RF output power with low distortion. A highly effective noise gate (downward

expansion) with front panel level and delaycontrols smoothly removes annoying back-ground noise picked up during speech pauses.

The results? You’ll be heard and under-stood. Powerful, highly intelligible speechgives you a commanding presence thatslices through DX clutter!

You can use any transceiver and with itsUniversalMicTM Interface, you can usealmost any microphone (high/low imped-ance, dynamic and electret) with the MFJ-653, regardless of whether or not the

microphone was designed for your particulartransceiver.

MFJ brings Pro Audio to ham radio! MFJ makes sophisticated Pro Audio

gear user friendly, affordable and RF bullet-proof. MFJ adapted Pro Audio’s heart andsoul to ham radio communications.

The MFJ-655B all-in-one audio consolegives you Pro Audio processing that makesyour audio professional sounding.

It gives you all the capabilities you'llever need . . . 8-Band Equalizer . . .Downward Expansion noise gate . . . cleanCompressor . . . smooth Limiter . . . lownoise Preamp . . . universal microphoneinterfacing . . . impedance matching . . .level control . . . and RF/audio isolation.

Its processing is so smooth and transpar-ent, no one will detect its presence. Allthey will hear is your outstanding audiothat brings you unsolicited compliments.

A built-in headphone monitor lets youhear improvements as you make them anda VU-meter lets you accurately adjust levels.

An auxilary input lets you use otheraudio sources and a push-to-talk jack letsyou use microphones without PTT.

The MFJ-655B uses the Analog DevicesSSM2166. This professional quality audioconditioner gives outstanding performanceover an exceptionally wide bandwidth withvery low noise and very low total harmonicdistortion, typically .25%.

An 8 Band Equalizer lets you adjustyour voice for full quality ragchewing audioor powerful, pileup penetrating audio.

An adjustable Downward Expansionnoise gate gives you transparent back-ground noise reduction.

A clean, low-distortion Compressorgives you more powerful, richer, fullersounding speech with more talk power.

A smooth Limiter keeps instantaneous audiopeaks from overdriving your transmitter andprevents SSB distortion and splatter.

Front panel controls let youeasily adjust input and output levels.

You can use nearly any micro-phone with any transceiver with itsUniversal Mic-Interface, pre-amp, mic elementvoltages, impedance matching and PTT jack.

Plug in your headphones to hear your rig’sreceived audio or plug in your MFJ, Heil orcomputer boom-mic headset to talk and hear.

New! The Compressor and Equalizercan be used independently of each other.

8 Band EqualizerThe MFJ-655B voice band equalizer

divides the speech frequencies into eightbands -- 50, 100, 200, 400, 800, 1600, 2400and 3200 Hz. You can increase or decreasethe gain of each band by 16 dB.

For ragchewing, you can adjust for rich,full quality audio. And for Dxing, you canincrease the high and reduce the low fre-quencies for a highly intelligible signal thatlets you punch through DX pileups.

You can turn ordinary, even poor micro-phones into pricy professional sounding ones.

Equalization compensates and improvesyour entire audio chain -- from your voiceto your microphone and through your radio.

Downward Expansion noise gatingDownward expansion noise gating elim-

inates or greatly reduces background noisewhen you stop speaking -- no more amplifierfan noise, dogs barking, kid’s music or traffic.

Downward expansion is a professionalaudio technique. When you stop talking itsmoothly attenuates low-level noise byreducing gain instead of abruptly cuttingoff like a noise gate -- background noisesmoothly vanishes.

You control the level at which downwardexpansion starts and the delay when it ends.

Clean, Smooth CompressionNatural unprocessed voice has peaks and

valleys. The average power of SSB speechis only 15 to 30 percent of peak power.

If instantaneous peaks are reduced, aver-age power increases significantly.

The superb Analog Devices SSM2166provides smooth, clean, almost transparentcompression over a very wide bandwidth.It reduces speech peaks as much as 15 times.

Just a small amount of clean compressionis impressive and gives you more powerful,richer and fuller sounding audio.

For DXing where every ounce of powercounts, you can use more compression toincrease average power.

Most of the speech power is in thelower speech frequencies.

Attenuating these lower frequencieswith the equalizer reduces their power.

This lets you increase compression forweaker high frequencies -- where most ofthe speech intelligibility lies.

The MFJ-655B compressor does asuperb job in creating an exceptionallyclean, higher average power SSB signal.

Limiting -- splatter preventionIf occasional large audio peaks exceed a

fixed set level, the compressor's limitingfunction quickly attenuates them.

Limiting prevents over-driving yourmicrophone input, transmitter and amplifiercausing SSB distortion and splatter.

In the MFJ-655B, compression and limit-ing work jointly to provide a level, constantoutput.

Universal Mic-Interface/Pre-AmpStandard XLR, 8-pin round or 8-pin

modular microphone jacks are provided onthe back panel. You can also plug in yourMFJ, Heil or computer boom-mic headset.

A PTT jack for a foot switch or other letsyou use microphones without push-to-talk.

Its Universal Mic-Interface lets you useany mic with any radio. Internal jumpersconfigure any microphone to any radio.

A front panel controlled low noise pre-amp gives you up to 20 dB gain.

Select 600 Ohm, 200 Ohm or Hi-Z inputimpedances to match dynamic, electret orhigh impedance crystal/ceramic microphones.Has 8, 5, and 11/2 VDC mic voltages.

“What did you say?”Can you hear but . . . just can’t always

understand what people are saying?As we get older, high frequency hearing

loss reduces our ability to understand speech.Here’s why . . .

Research shows that nearly half thespeech intelligibility is contained in 1000 to4000 Hz range, but contains a miniscule 4%of total speech energy.

On the other hand, the low frequencies,125 to 500 Hz have most of the speech energy(55%) but contribute very little to intelligibili-ty -- only 4%.

To dramatically improve your ability tounderstand speech, you must:

First, drastically increase the speech ener-gy above 500 Hz, where 83% of the speechintelligibility is concen-trated.

Second, drastically reduce speech energybelow 500 Hz where only 4% of speech intel-ligibility lies.

The MFJ-616 splits theaudio speechband into fouroverlappingoctave ranges

centered at 300, 600, 1200 and 2400 Hz. Youcan boost or cut each by nearly 20 dB.

A balance control and separate 21/2 Wattamplifiers let you equalize perceived loudnessto each ear so both ears help.

By boosting high and cutting low frequen-cies and adjusting the balanced control, speechthat you can barely understand become highly

understandable!Even if you don’t have high frequency hear-

ing loss, you’ll dramatically improve your abil-ity to understand speech.

QST for April, 2001 said “I expected a subtleeffect at best, but I was astonished . . . The resultwas remarkably clean, understandable speechwithout hissing, ringing or other strangeeffects . . . made a dramatic improvement . . .”

Wipe out noise and interference before itgets into your receiver with a 60 dB null!

Eliminate all types of noise -- severepower line noise from arcing transformersand insulators, fluorescent lamps, light

dimmers, touch controlled lamps, com-puters, TV birdies, lightning crashes fromdistant thunderstorms, electric drills,motors, industrial processes.

It’s more effective than a noise blankerbecause interference much stronger thanyour desired signal can be completelyremoved without affecting your signal.

It works on all modes --SSB, AM, CW, FM, frequences fromBCB to lower VHF.

Null out strong QRM on top of weakrare DX and then work him! You cannull out a strong local ham or AM broad-cast station to prevent receiver from over-loading.Use MFJ-1026 as an adjustable phasing

network. You can combine two antennas togive you various directional patterns.

Null out a strong interfering signal or

peak a weak signal at a push of a button. Easy-to-use! Plugs between transmit-

ting antenna and transceiver. To null,adjust amplitude and phase controls forminimum S-meter reading or lowest noise.To peak, push reverse button.

Use built-in active antenna or an externalone. MFJ’s exclusive Constant AmplitudePhase ControlTM makes nulling easy.

Automatic gain control (AGC) keepsaudio level constant during signal fade.

Tunable bandpass filtersNarrow band signals like CW & RTTY

jump out of QRM when you switch inMFJ’s tunable FIR bandpass filters.

You can tune the center frequency from300 to 3400 Hz, and vary the bandwidthfrom 30 Hz to 2100 Hz -- from super-tightCW filters to wide razor-sharp Data filters.

You can use two tunable filters together.

For example, tune one tomark, one to space and setbandwidth tight for a supersharp RTTY filter.

You can tune the lower cutoff frequency200 to 2200 Hz and the upper cutoff fre-quency 1400 to 3400 Hz. This lets youcreate custom filters for voice, data andother modes. Signals just 75 Hz away lit-erally disappear -- they are reduced 57 dB!

MFJ invented the tunable active anten-na! Numerous copies have been made with-out success -- including most recent ones.

Why? Because MFJ has made continu-ous improvements where others have not.The MFJ-1020C has been completelyredesigned with new technology.

New technology uses a cascode FET/bipolar transistor and a gigahertz bandwidthbuffer.

It improves gain and selectivity,reduces noise and intermod, and is NOTprone to self-oscillations that can severelydamage your receiver.

With the MFJ-1020C tunedindoor active antenna you’llrival reception of outside wireantennas hundreds of feet longand pick up signals loud andclear from all over the world.

World Radio TV Handbooksays MFJ-1020 is a“fine value . . .fair price . . . bestoffering to date . .. performs verywell indeed.”

MFJ’s unique

tuned circuitry minimizes intermod,improves selectivity and reduces noise out-side the tuned band. You can also use it asa tuned preselector with an external anten-na.

Covers 0.3 to 40 MHz including VLF,AM broadcast, all shortwave and all ama-teur radio bands.

LW/MW/SW Preselector/Tuner

MFJ’s new Passive Preselector hasextremely high dynamic range! Itimproves the performance of nearly any HFor shortwave receiver/transceiver. It vastlyimproves the most expensive receivers.Especially helpful to those with broadbandfront-ends that are prone to overload.

Protects your sensitive receiver inputfrom damage (including switching diodesand attenuator resistors) caused by verystrong signals from multi-transmitter,multi-band operation -- contests, field-day,

nearby hams, CBers, TV/FM/AM stations.It eliminates phantom signals by sup-

pressing strong out-of-band signals thatcause intermod, blocking and cross modu-lation. Completely eliminates second

order intermod problems. MFJ’s unique Hi-Q series tunable cir-

cuit gives you superb performance. The tunable series tuned circuit works

into a very low impedance formed bybroadband toroid transformers.

Has narrow bandwidth, excellent stop-band attenuation, very low loss, constantbandwidth and gain over each band.

Excellent attenuation in adjacent bands. The entire 1.6 to 33 MHz HF band is

covered in five overlapping bands. An air variable tuning capacitor, 1.8 to

1 tuning range and a vernier reductiondrive gives you precision tuning.

MFJ-890 DX Beacon MonitorGet up-to-the-minute worldwide DX

band conditions in minuteson 14, 18, 21, 24, 28 MHzbands using the Inter-national Beacon Networkof 18 transmitters around the world!

MFJ's DX Beacon Monitor lets yousee which beacon you're hearing on yourtransceiver -- an LED lights on its worldmap to show you the beacon locationand where to point your antenna.

It's fascinating to hear and watch eachbeacon location light up as they becomeactive across the world. Great forDXers, contesters, ragchewers andSWLers.

The International Beacon Network pro-vides a reliable source of signals for deter-mining HF propagation 24 hours a day.

It consists of 18 beacons around theworld. Each beacon transmits on 14.1,18.11, 21.150, 24.93 and 28.2 MHz. Thetransmit sequence moves westward fromNew York across North America, Asia,Pacific to Africa, Europe, South America.

On each frequency, each beacon trans-

mits for ten-seconds -- its call sign at 22wpm CW and a one-second dash at 100watts and three one-second dashes at 10, 1,and 0.1 watts.

When each beacon completes a trans-mission it goes silent on that band andswitches to the next higher band.

For more information see Oct/Nov, 1994,Sept, 1997 QST and Jan 1999, Sept/Dec2001, Jan 2002 Practical Wireless of U.K.

The more beacons you hear, the more

open the band is to different parts of theworld.

The more dashes you hear per beacon,the better the quality of propagation and themore robust the band is. If you hear the100 milliwatt dashes from many beaconsyou know the band is wide open!

In just three minutes you'll know howband conditions are worldwide.

You don't have to copy CW at 22 wpmto identify a beacon. As you hear a bea-con, an LED instantly lights on a worldmap to show you its location. You can pos-itively identify each beacon -- even if thesignal is weak, fluttery or distorted.

The MFJ DX Beacon Monitor has abuilt-in WWVB atomic clock receiver toprovide ultra precise synchronization withthe GPS-synchronized beacons. You alsomay manually sync the Monitor (theMonitor is not a receiver).

MFJ-890 is a self-contained standaloneunit. 63/4Wx51/4Hx3D”. Use 12 VDC or 110VAC w/optional MFJ-1312D, $15.95. Noantenna/radio connection required.

Thissuper highperform-ance ama-teur radioATV

transmitter module is capable of putting outa whopping 4.5 Watts! The RF power out-put is controlled by an analog potentiome-ter from near zero output to 4.5 Watts max-imum. Current draw varies with powerlevel selected.

Frequency control is provided bymeans of a digital integer-N, phaselocked loop. Dual PLLs provide a fre-quency locked video carrier and an audio

sub-carrier. Transmit frequency is selectedvia a four position dip switch. Four stan-dard US ATV frequencies 426.25, 427.25,434.00, and 439.25 MHz on channels 58, 59and 60.
