VLA MONTHLY PROGRESS REPORT
April 9, 1974
Narrative Report
1. Site and Wye - The Joint Venture completed Title I work and
Title IIeffort is about 50% complete. The Title II work for the
first contractwas delayed approximately six weeks due to revision
of the antennastation locations. A Notice of Intent to Solicit Bids
on this firstcontract has been issued and the target date for
issuing the IFB isApril 22, 1974 with bids being due on May 22,
1974.
The well provided for under subcontract VLA-22 has been
satisfactorilycompleted at a depth of 402 feet with the exception
of test pumping,grouting and disinfection.
Sufficient ties, rail and fittings have been procured for the
firstyear's construction.
2. Antenna Division - E-Systems, Inc., has accelerated their
designeffort which has resulted in the completion of the concept,
analysis andengineering phases of the design program. This has
allowed additionalpersonnel to be assigned and utilized in the
preparation of drawingsand specifications. Progress in specific
areas is as follows:
a. Antenna- Structural and mechanical design is essentially
complete.Specification documentation on the procurement of long
lead itemshas been prepared and approved by AUI. Major assembly,
drawings,layout drawings, servo analysis, logic diagrams and servo
parametersare near completion or have been completed.
b. Antenna Assembly Building - E-Systems has prepared and
revisedspecifications for the building and resubmitted the
specificationsand drawings to AUI for approval.
c. Transporter - Hydraulic circuit design, design analysis and
componentselection is in progress. Layout of equipment and initial
con-figuration drawings are underway.
3. Electronics Division - Principal effort is being directed
towardsprocurement of the prototype electronics system. Orders have
beenplaced or are in the process of being placed for most of the
highcost, long lead items. Progress in specific areas is as
follows:
a. Feed Mounting Ring - Electrical specifications have been
completedand mechanical design is underway. The feeds are being
bid.
b. Front Ends - Orders have been placed for the parametric
amplifiersand Up-Converters. Design layout is continuing on
componentswhich are not mounted in the dewars.

VLA Monthly Progress ReportPage 2
c. Local Oscillator - Advanced testing of the breadboard system
ofthe local oscillator and modems revealed the need for some
minorsystem modifications which are underway.
d. Transmission System - Orders have been placed for the modem
units.
e. Waveguide -An order has been placed for 1,250 meters of
TE01circular waveguide. Tests have begun on an experimental
designfor waveguide coupling that would utilize the full 60 mm
diameterof the waveguide. It is expected that this effort will
eliminatethe need for tapered sections.
f. Digital Delay and Multiplier System - Most major procurements
arein process.
g. General Electronic System Design - New block diagrams have
beencompleted which incorporate several minor modifications
thatresulted from tests with the breadboard system and
experiencewith the prototype electronics design.
h. Division Staffing - Two vacancies on the VLA Engineering
Staffhave been filled. These are a digital engineer for the
monitorand control system and a front end systems engineer.
4. Computer Division - The major effort in the VLA Computer
Division hasbeen the finalization of the technical evaluation of
the proposals forthe synchronous and asynchronous computers. This
effort is nowcomplete and a contract award is projected prior to
the end of April.
5. Project Management - Three vacancies in the Project
Management Staff havebeen filled. They are Purchasing Officer,
Contract Administrator,and an assistant who will provide liaison
between the various sub-contractors and the NRAO technical
areas.
