2. One hundred and eleven of the one hundred and seventeen re-
jected RR-390/URR Receivers were repaired by FTS, and the remaining
six were accepted in C-3 condition.
3. After many delays the State Department has finally installed
their keylines to their equipment, and the back-up Microwave System
between Langley and State Department has been tested and is now ready
for operational use.
4. Two technicians have departed for PCS assignments. Nine
technicians were on domestic TDY, and three technicians returned from
extended TDY's in he latter part of the month. Eight of our
technicians were i CREI Electronics Course at LTS, nineteen were
in various stages of training , and five technicians are in KG-13 25X1A6a

MEMORANDUM FOR THE RECORD

FROM
SUBJECT : Trip Report --SSB MUX Installation
25X1A6a _ - New - Receiver Station
25X1A6b
25X1A6b
25X1A6b 1. During 19 October through 4 November 1964 the undersigned supervised
and assisted the - technical staff in the installation of the 25X1A6b
25X1 A6bend of the SSB MUX System.
2. Most of the major items for the project had been received prior to
arrival of the undersigned. ThM engineering staff had already started 25X1A6b
work on the installation by making Macs available, installing the R-390/A
receivers and SBS adapters at the receiver station and placing the two 204 C-1
linear amplifiers and associated exciter rack in position in the west wing of
the transmitter building. The new G.E. power panel for the west wing was
mounted but not wired due to unavailability of proper size wire. The wire was
on order with a local vendor with promise of delivery in five days.
3. At the receiver site, the technical staff between the 20th and the
30th of October accomplished the installation and wiring of the Northern Keyers
and converters in a new rack, ran new control cables between the Northern equip-
ment, main frame and patch panels, fabricated a 36 position D.C. panel to control
the input and output loop currents of the Northern Keyers/converters, fabricated
and wired new patch panels for exclusive use on this system at the radio control
position, installed new power wiring to all racks and ducting to accommodate
both the new control and power wiring. All tone Keyers and converters were
bench-checked for frequency accuracy, adjusted and tested back-to-back prior to
final installation and use on the system. The sub-carrier assigned to carry the
Keyer tones over the microwave was accurately aligned and tested for uniform
bandwidth response (0-3DB) over 1,000 to 3,000 cps., low noise, distortion and
cross talk.
4. At the transmitter site during the same interval, the two 204 C-1 linear
amplifiers and associated rack containing the SBE exciters were installed, new
power cables runs made between the equipment and the new G.E. power panel, new
control cable linking the SSB equipment with the microwave, main frame and patch
- panels installed and new ducting runs made to accommodate the new power and
control cables. Also, the two baluns for use on rhombics 10/11 were installed
on the H-frame supporting the feed lines of these antennas together, with runs
of new RG-17/U coax cable.
5. The transmitter end of the system was completed on 27 October. Initial
testing of the 204 C-1 amplifiers and exciters, under two tone conditions, was
started immediately. All necessary adjustments, measurements, and calibrations
were made at this time taking advantage and opportunity to brief and train the
transmitter personnel.
