1. Project Description:
NNW
25X1A5a1 has developed a breadboard model
of a spread spectrum VHF communications system that may satisfy our
i.+ requirement for a short range, body concealable system featuring
minimum risk of interception by hostile receivers.
25X1A5a1 Before further development is sponsored, we desire to test the
? system under simulated field conditions. The present breadboard
will be repackaged, put on a frequency in the 300 Mc/s band, and field
tested in Washington, D. C.

25X1A5a1
When I arrived on 27 July, Messrs. were ready to
run some field tests on the transceivers. .+ac transceiver was con-
nected to a ground plane antenna that in turn was attached to the roof
of the car. We ran tests around the city of during the
afternoon and well into the evening varying the distance and obstacles.
Trees tended to limit the range more than buildings. Ranges between
.7 mile and 3 miles were obtained. The voice quality was good. The
system as a whole seemed to operate quite well. They are now ready
to bring the transceivers to Washington to demonstrate and to leave
them with us for evaluation. They will want to run some tests around
Washington prior to the demonstration to determine if the new e
n
yiron-
25X1A5a1ment will affect the system. The time all this will happen depends
on Allllllllllllllllll luck in getting airplane reservations during the airline
strike.
25X1A9a
The following day we discussed the system; when and how we could
demonstrate it; and what possible applications it may have. I reminded
them that they owed us an interim report as well as the final report.
They said they would deliver these reports with the'units.
I also learned that there is no inherent limitation to using the
spread spectrum system with the RS-520. This could provide the required
security necessary to use the RS-520 with systems such as
