The contractor we. told of the arui 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. was told that unless the remaining coder* could be r their use by unskilled operators, we could not cons coder icL2Hantity.

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.
