had been encountered during the preliminary
15 to 27 Mnrch 1959. Principal among these was coder unreliability,
evidenced by erratic spacing between dots and dashes. The contractor
was told that the tun electrical defects which arose during the tests
together with the coder faults, must be remedied in the remaining
.it prototypes. On one unit (Serial 514) RF was leaking back into
the keying amplifier and causing improper operation, and in the other
(Serial 515) the pit-output inductor was intermittent.
25X1A5a1 3. said the coder problem was probably due to incon-
sistent tape advance, especially when ttimilliSH key is depressed. In
one of the coders recently completed at this effect had been
quite pronounced, and a remedy is now being investigated.

the speed and extent of the key downstroke.

had arisen.) The contractor had found that the field expedient used
by as (installation of an RP choke in the keying line) has eliminated
that feedback, and the eight keying amplifiers being assembled at
are being rewired to include this aodification. The inductor trouble
has never been encountered atM and was not present in the four
tranenitters checked by the writer. was told we would watch
closely for this problem in future field tests and advise him if it
arose again.

that it uould take about 6 months to ooze up with a final layout and build
one or two systems, but that production in lot* of 20 or so per month could
