a. General
Technical progress is good with a few problem areas. - is 25X1A5a1
estimating March 1966 delivery. A proposal has been received from
for a new task for $17,178.00 to cover detailed planning of
We ie test experiment and logistics. - requested through us 25X1A5a1
a letter from the Office of Logistics with a check for the residual
inventory of Task Order ii. All GFE on Task Order 4 has either been
returned or transferred to Task Order 6.
b. Security
25X1A5a1 new security officer, was briefed by
us now that his clearance Wass established. A new
inspector has been assigned He reportedly wan t s o see 25X1A
25X1A5a1 "everything". We told- to call OL/Security immediately if the
inspector demanded access to our contracts. Selective Service is trying

c. Base Station
The receiver site checkout is complete. Minor changes in the ACI
subcontract bit synchronizer resulted in a 1/2 to 1 db improvement in
system performance. Only one failure, a diode, has occurred in several
months of receiver testing. The transmitter site is completed. Per-
formance tests are being continued on the base station to ensure proper
system operation.
d. Field Station
(1) Power Amplifier
The power amplifier is completed. It provides 50 watts out
from -30 to +50? C with a 22 volt supply. Overall efficiency is
greater than 34 percent at 30 Mc/s. Collector efficiency is
greater than 4+7 percent. The unit has been tested from.6 to 30
Mc/s but will operate from 2 to 32 Mc/s. It is open and short
circuit stable with ALC protection.
(2) Antenna Matching Unit (AMU)
The AMU is assembled (finally) and electrical components are
mostly installed. It is to be checked out soon.
(3) Coder/Keyer Simulator
The unit was modified to match the CK-31- mechanical interface
on the receiver/exciter.

(4) Battery Pack
The battery pack is mechanically fabricated. The mechanical
interfaces with other field unit components are poorly done and
will be improved or done over before final painting of the unit.
The battery is a 1 AH GE cell. Surprisingly, using this battery
to encode messages with the CK-34- only uses .02 AH of the 1 AH
capacity, thus not degrading the "mission" life.
(5) Receiver/Exciter
The majority of the technical problems are being experienced
with this unit. About 18 August, all microelectronic circuit
25X1A5a1 designs were let to for layout. Delivery of
the completed units is an icipa e in early October. The tuner
has been modified by adding a fourth switch deck. The switch deck
was previously in the AMU and caused a mechanical alignment problem
25X1A5a1
during assembly. A subcontract with for fabrication of 25X1A5a1
epoxyed modules of TI flatpacks is not going well. - is
apparently not as skilled as they thought they were and modules
25X1A5a1 are being received by - with internal shorts and some
wiring errors. The contract is fixed price, so-must com- 25X1A5a1
25X1A5a1 plete to get paid. - is watching the contract closely. A
more serious problem has arisen in the recognition code used in
the system. The 1OP1023 code employed works as a confirm code.
When inverted for sounding however, it will trigger the confirm
indication on an adjacent channel in the receiver/exciter. This
happens because of differentation of the RF waveform by the slope
of the bandpass channel filter characteristic and the property of
all M-sequences and the 1OP1023 sequence in particular that the
sequence differentiated is the complement of the original sequence.
25X1A5a1 is studying the problem and has recommended the use
of a lengt 89 non-M sequence. This can be generated with existing
logic with only one wire being changed. This non-M sequence appar-
ently does not fail under differentation and is presently being
thoroughly investigated. Meanwhile, a hold has been placed on
further assembly. . .

further assembly of the digital portions of the receiver/exciter
until the problem is found. (It is interesting that this differ-
entation phenomenon will account for the occasional adjacent band
false confirmation found during the Task 4 field tests. The code
employed there was a 5P31 M-se u.ence. The "fix" was using a 33
bit non-M sequence although did not know at that time w X1A5a1
that fixed it.)
e. Future Work
25X1A5a1 Field tests should begin in April IQ66- To prepare for them
as proposed a 17,000 effort to generate a detailed field
er to ensure the collection of an adequate amount of meaningful
data to ensure our understanding of the system under operational
circumstances.
