To add to Robert's remarks, aboard the Com7thFleet flagships, USS
Providence and
USS Oklahoma City, the transmitter room had 8 WRT-2's, 4 URC-32's, and 1 TMC
1 KW transmitter. We had a single receiver in the room, a WRR-2. Two WRT-2's
were keyed 24/7 transmitting 8 channel mux RTTY back to the nearest shore
station. The receivers in Radio Central were mostly R-390's, a few
paired with CV-157 for
mux reception. Time - 1963-1965.
