MONTHLY REPORT
ENGINEERING SERVICES BRANCH
December 196+
1. Surveillance Equipment Support
a. A four man team consisting of members of OC-OS and OC-E a_J "7
conducted a range test with representative samples of two-way voice radio equipment. The purpose of the test was to provide ,~\
information on actual communicating ranges that can be expected from the various equipment; this information will be included in
Technical Bulletin No. 41, Revised. All testing was done in the
Washington Area and lasted two days.
25X1A5a1 b. We are attempting to find the cost and complexity of dual
channeling two-way voice equipment presently in
25X1A5a1 stock. It appears that does not have this infor-
mation readily available u wen we do determine the facts, we
will decide who modifies the equipment,
c. A series of memos to MSB has resulted in bringing about
three (3) different lists of stock numbers for the three (3)
classifications of equipments arising from the decisions to:
(1) go narrowband
(2) go multiple frequency.
The three (3) main classifications of this type equipments are:
(1) wideband
(2) Narrowband
(3) narrowband-multiple frequency
2. Shelf, sliding, OC Standard, SH-5 - A small project was worked
up for the purpose of bringing into stock a sliding shelf suitable for
general use in the standard equipment rack. There are a number of com-
mercial sliding shelves available but none are completely acceptable.
A description and drawing were made and a requisition prepared. If all
goes well at the Office of Logistics, we can expect a standard SH-5 in
stock in about three or four months.

3. HFL-1000 Linear Amplifier - The transformer sub-contract,
25X1A5a1 has developed a replacement for T-203,",, e1
that he claims is suitable. We will receive a sample and have it ~r
25X1A5a1 tested at early next month. If suitable, - Y-Uv 25X1A5a1
25X1A5a1 - will ship one hundred and seventy five transformers, no cost, r
which we will then distribute to the HFIr1000 owners.
4. Kahn Single Sideband Remote Controlled Exciter - The first
_ unit of an order for thirty five was received at the end of this month.
The contract specifies evaluation and acceptance of the first two
units prior to manufacturing the remainder. We plan to test the model
25X1A6a on hand connected to and operating with the 208U-10 linear amplifier
at the
25X1A5a1
25X1A
5. Narrow Shift Converter - Using a frequency counter with
a print-out recorder the RTTY signal from one of our stations in Central
America was monitored to determine the carrier frequency drift both in
the transmitter and the receiver. Over a number of hours of monitoring
the maximum drift noted was 30 cycles in one hour. This was discussed
with - to determine the feasibility of reducing band width and
therefore the number of filters and related circuitry of the Narrow
Shift Converter. As now planned the converter will cover 1.4 kc in
seven increments. Additional tests are planned to obtain more data on
the drift characteristics of our typical communications circuits.
--25X1A8a 6. =Fly-Away Packages - Four GNT Morse Keyers were ordered for
use with the beacon transmitter which is a part of these packages.
7. Transportable Communication Systems I & II - The mock-ups of
Systems I and II were completed and exhibited to members of the Engineer-
ing Staff for critique.
8. Project "8-PAC" - Preliminary design work was started on this
project for presentation to the equipment Board meeting in January.
"8-PAC" is an air-transportable base station completely equipped to
provide full duplex RTTY with on-line crypto to seven field stations
and one trunk outlet.
_ 9. Thin Route Tropo - Correspondence is being exchanged with
25X1A6a NATCA in an effort to secure frequency authorization which is compatible
25X1A6 b with the range of the equipment and the frequencies available for our
use on a to -path.
2.5-X1 A2g
10. Project - After a series of meetings it was decided
25X1A5a1 to have submit a proposal for the Communications and
Navigation gear and a test program. The communications equipment
25X1A5a1 proposal will be based on a Work Statement and equipment list received
from the

1. Selector Magnet Shield - Delivery of 50 pre-production
shields is scheduled for April 1965. The unit cost of these items
will be 69.00 each. The production model shields have not yet
been priced out. This figure should be available during the next
reporting period.
2.5X1 A 2. _ - Production is on schedule for February delivery.
3. Model R-80 Optical Repeater - Tests have been completed and
the unit was found to operate very well. Specifications are being
written for quantity procurement of this type device for direct replace-
ment of Sigma Relays.

)+. Model R-85 Optical Inverter - KW-26 - Two units are operating
satisfactorily after three weeks on an operational circuit at Langley
and One unit of four (4) became inoperative after a few
hours use at Specifications are being written for pro-
curement of this type of device for all KW-26 units world-wide to
alleviate existing maintenance problems. N.S.A. has indicated interest
in this same type device. It is a replacement for Sigma-type Relays,
with inversion of the Mark and Space Signals.
5. R-100 (A) - The R-100 tested successfully and indicated better
than 110 db attenuation in the worst conditions. Twenty units are due
in early January 1965, for use with five (5) special screen rooms.
Specifications are being written for procurement of this type device
for shield rooms and standard station filter applications, replacing
RFI filters.

quotes during January on a console requirement. Cable format tests were
not instigated during December as planned, but we hope this can be
accomplished in January 1965.
25X1A5a1 7. I Solid State Relay - requested approximately 15.00 25X1A5a1
per unit for modification components. This is considered too great an
expense for what we gain and therefore modifications will not be attempted
25X1A5a1on our 312 units. _ will be notified.
8. Morse to Baudot Converter - Model 670 - Tests have been com-
25X1A9a pleted by Mr. and the units are to be returned. The input
card was again burned out by improper signal line battery connection
with no limiting resistance. A fuse will be required on any future unit
to prevent this type of failure.

9. KW-7 TWX - Two TWX installations were made in
for purposes of testing with the KW-7. One installation had to be
removed when it malfunctioned and could not be repaired on site.
Discussions are now taking place between OC-E, NSA, AT&T and C&P in
an effort to make this test installation a government standard rather
than being peculiar to CIA. Nine of the safes ordered from Mosler
were delivered and placed in stock. The remaining fifteen will be
delivered next month, but due to lack of KW-7 cables, will not be
complete.
10. KW-7/Fixed Plant Installation - Beginning in January WES
will have two pre-production rack mount installations built under a
service contract. Approximately eight weeks will be required for
completion, at which time the units will be operationally, and possibly
TEMPEST, tested. Production units will then be built using the speci-
fications derived from the pre-production models.
12. KG-13 Program - Six ?SEBIT-36 modems were ordered for
use with KG-13 links.
13. LBAC-250 6 circuit Transmitter Cabinet - Manpower shortages
have necessitated a slowdown in modifying the LBAC-250 now in Alcott.
The final version of the modification was done on a cabinet at Franconia
by T&I personnel and developed no problems in operational testing. The
MWO will probably go to press in late January.

16. Design of Dissemination Circuit - A dissemination circuit
is presently under design for the Langley Signal Center to facilitate
traffic flow between the Special Signal Center and other offices within
the building.
17. M-28 Stunt Box Design/NPIC - A M-28 Stunt Box modification is
being designed for NPIC to provide a more reliable method of vertical
tabulation of page copy. This project has slowed down due to lack of
parts from the Teletype Crop. All required parts are on order.
18. KAB 149/150 NSA KW-26 Filter Installation (MW0 89/90) - The
MWO concerning the additions and deletions for KAB 149/150 is ready
for distribution to the field. However, NSA has put a hold on all
filters for corrective action on a minor mechanical problem.
19. Iron Curtain Stations - Wiring diagrams and cable chart
information on the rack-mounted stations is being formulated for
pouching to all posts.
20. HW-28 Acoustic Attenuation Kit (JACT) - An acoustic atten-
uation kit has been designed for use with the HW-28. The kit consists
of a fiberglas and aluminum enclosure to be placed around the HW-28,
a polyester pad underneath the HW-28, and drapes to be hung in front
of and to the sides of the HW-28. Three prototype kits have been
assembled and specifications are being written for the construction
of approximately fifty additional kits. Commercially available
enclosures are being investigated to satisfy this requirement.
a. The entire Sideband MUX Program is currently under review
to determine what measure of assistance we can provide the field to
get it underway. Present status and problems were discussed at a
meeting attended by Chief, OC-AFD and members of OC-E
b. - New Receiver Building - This project was initiated.
on 18 December 1964 during a briefing by Mr.~ Chief, OC-AFD.
OL/RE&CD was briefed on 23 December 1964. Cost estimates prepared
by RE&CD,,and a single line drawing of the proposed building were
presented t See Memos for the Records

(1) A&E drawings for the - basement-located Comcenter 25X1A6a
were received via the FBO, Washington. The recent decision to
install a shielded enclosure concurrently with the actual reno- 25X1C
vation necessitated changes to the previous scheme. The _
Mechanical Engineer is revising the air conditioning portion and
will specify the actual equipment. Sixty kilowatts of power will
be required to operate the 35 ton air-conditioning system with
the required fan coil units. This presents a demand load of
130 KW for the joint Comcenter and will require an additional
100 KW generator to supplement the 100 KW unit provided by the
Department. The revised power requirements are being drawn up
