Field Trip Report - ED-271 Task Orter420---
1. On 4 November, I visited to discuss the
details on the =ogress of the sUbieet contract. RenreRAnting

50X1
50X1
2. As the program now stands intends to provide us 50X1
with one model of a transistor rece ver operated in the frequency
range of 2-8 megacycle in 2 bands. This represents a departure
from the original p1an,5roviding us with theoretical data
concerning transistors and their application. This portion of
the program should be completed by the end of this calendar
year at which time a ? roximately $10,000 will remain allocated
to this contract. has suggested that this $10,000 be 50X1
utilized to cont ransistor application investigation for
one more year. Essentially, this means that the present program
would be drastically cut and that we would receive reports
providing information concerning'----4velopment in the transistor 50X1
field both as to circuit application and transistors for transmitter
use. In the event that we decide to accept this program, will 50X1
ask for a one year extension to the contract without additional
funds. As an interim measure, is going to request a 50X1
one month extension which will permit the Project Group to spend
the remainder of this year in active construction of the model
receiver. The one month extension would be required for the
preparation of the final report.
3. I supplied with some rather indefinite figures to
serve as a specification in order to Obtain a fairly firm idea
of the order of magnitude of the funds required for developing
the pre-production models of a transistor receiver to operate in
the range of 3-12 megacycles. will_nrepare a rough estimate
as to the cost of this program. me engineers are fairly
optomistic as to Obtaining the 12 megacycle response, however,
their bid will be based on a receiver which will function from
3-12 megazycles but BOY lack a satisfactory noise figure above
8 megacycles. ,as asked to provide the following
information:
. Cost of 10 Pre-production Models
b) Cost of 10 Production Prototypes, including
tooling costs
(c) Estimate date of completion

It Should be borne in mind, that the costs which will be supplied
us will provide only an order of magnitude and cannot be
considered a direct quote.
4. An engineering model of the 2-8 megacycle receiver is
now being fabricated. The receiver without batteries will be
enclosed in a ease 6" x 3" x 1 1/16". The receiver is expected
to have a sensitivity of 15 microvolts with a 10 db signal to
noise ratio at one milliwatt output into a 4,000 ohm load.
5. of the Fre (?) Production Design Group
demonstrated a receiver which would operate in.the range of
45 to 50 megacyclesttilizing hand-picked transistors. This unit
excluding batteries was somewhat larger than a cigarette pack.
A battery pack approximately one inch square by 2* inches vide
was being designed to plug into the base of the receiver. The
receiver was crystal controlled using a crystal manufactured by
Hunt, Carlisle, Pennsylvania. The crystal was encased in a
metal container of the mmne size as the The
group working on our receiver project believe that an improved
version of this set could be made by using dual conversion and
junction type transistors similar to those used in the I.F. strip
of our model receiver. (The present unit uses a TR172 transistor
mixer and selected TA172 transistorsin the 4.3 megacycle IF strip)
It is felt that this unit could be readily adapted to a, multitude
of frequencies by use of a plug-in BF section. This receiver was
of RCA design specifically intended for use with the PRC-10 FM
transceiver. The engineers pointed out that stleh units had been
made to operate as high as 900 megacycles with, extremely carefully
selected transceivers. (Ncrkwecessa.r,Iti o'cOAiVac,44VC Ch"5101 .
In general, I was very favorably impressed with the
worI was doing on our project as well as with their own
projec the development of transistor equipment. I believe
that a further investigation as to possible requir s for a
VHF or UHF receiver of the type being constructed by for
Agency use should be made. Pbssibilities which presen hemaelves
