SUBJECT Trip Report,
23 may 1957
1. This trip was made on 9 May 1957 for the purposes of visiting
to discuss project 50X1
status. Present were:
2. Discussion:
50X1
P-191A. Work on the low-band receiver is about 50% complete.
Drawings have been released to production, parts have been ordered,
and model Shop production has begun; It is anticipated at thistime
that there will be a delay in delivery of these items beyond the
contracted date of up to 60 days - due to a severe personnel turn-
over rate that the company has been experiencing of late. This seems
to have came to an end by the time of this visit with satisfactory
new personnel shifted to this Agency's programs.
These low-band units will be supplied with an airline-type
canvas carrying bag, slightly padded, for some degree of shock absorbing
qualities.
Promising work has begun on a regulated AC power supply for
the receiver. Utilizing Zener diodes and transistor circuitry ex-
cellent regulation is being obtained on the specified range of 75 -
140 VAC on a bread-board mockup. No problems are anticipated in
packaging this supply so as to permit insertion in the receiver battery
compartment. Finally, the canvas carrying bag will be provided with
accessory pockets for convenient carrying of spare battery or AC
power supply, and antennae.
50X1
P-1 1B. The high-band receiver development is just be-
ginning. Work presently is underway on the design of a new RF
front end covering the specified frequency bemui. Some discussion
was held concerning the advisability of going to khigher IF frequency
and it was decided to defer this decision until - Project 50X1
Engineer - can study the various problems involved in this matter;
at that time, a mutually acceptable IF frequency will be decided upon;
t6r..,u me Nix No.

MEMORANDUM FOR: THE RECORD
SUBJECT : Trip Report,
50X1
The form factor of the new unit was discussed; Since it
now govears that the low bend receiver configuration is adequate
for 1.at was decided to forego a modification
at tbis time unless considerable saving can be made in at least one
dimension; This does not appear possible at this time without
extensive mechanical re-design. A final decision will be made later
in the program.
50X1
P-144A4 The carrier switch prpposal was discussed and 50X1
stated that they were prepared to modify the power sway 50X1
Li-d-h-de isolation circuits without changing the price of the contract;
The modifications include design of a high efficiency, low drain re-
ceiver/power supply and insertion of capacitors on both bides of the
line, so as to provide a, balanced load and reduce the probability of
detection by a DC line check;
