The 18S-1 is a 20 channel HF transceiver good for 2 to 18 Mc.
The transmitter is a predictable 6AG7-1625-813 lineup, modulated
by a pair of 811's. With 1100 volts on the plate, the 813 delivers
about 100 watts to the antenna. The receiver is quite sensitive,
although a bit wide. Dynamotor power, this unit requires 28 vdc
at about 30 amps.
Collins R-388 receiver.
