The receiver-transmitter is a separate unit secured by the mounting in the airframe structure. It

contains the transmit and receive circuits of the radio set. All maintenance controls and indicators are

located on the front panel. A locking handle also at the front of the unit, is used to secure the receiver-

transmitter to the mounting. At the rear of the receiver-transmitter, a blower fan and exhaust arrange-

ment cools the unit during transmitting. All electrical connections are made through a multiple-pin

connector and three coaxial connectors, also at the rear of the unit. Two guide pins and two guide-pin

receptacles facilitate proper mating of coaxial and multiple pin connectors.
