Description: Radio Set 18S-4 is a HF airborne communications system for
air-to-air and air-to-ground communication. Normally, it is used in
aircraft operating at altitudes under 31,000 feet. The equipment
consists of a transmitter-receiver with self-contained dynamotor unit,
and antenna-matching network or automatic antenna tuner, and a remote
control unit. The transmitter-receiver operates on up to 20 crystal-
controlled frequencies on 10 tuned channels. Each channel can be used
for two frequencies that differ in basic frequency by not more than 1
percent. Frequency selection, as well as audio input and output, may be
remotely controlled by an autotune system consisting of a remote control
unit and interconnecting cable. Antenna Matching Network 180K-3 and
Autmatic Antenna Tuner 180L-2 are designed to match 52-ohm output
circuit of the transmitter to various aircraft antennas at selected
frequencies. Antennas of 45 feet or longer may be used. Radio Frequency
Cable RG-8/U is used to interconnect the transmitter-receiver and
antenna matching network or automatic antenna tuner.
