Features include mechanical digital clock (make by Numechron), station master power control, a remote antenna switch, a phone patch, connections for recording audio, connections for transmitting audio which has been recorded, a station ID timer, a wattmeter, an equipment control function, and an antenna rotator control.
Clock – A standard Pennwood Numechron 24-hout movement, with one second resolution.
"Power Master" station power control – Large black and red push buttons on the front panel operate a contactor in a separate cabinet that can be located up to six feet away from the C-4. This cabinet has eight 120 VAC outlets for control of station accessories, and two 240 VAC outlets for control of amplifiers or other equipment. A hidden "safety switch" can be used to disable the Power Master when the station is left unattended.
Remote antenna switch – Provides selection of up to five antennas, using only one feedline. Unused antennas are grounded, and a position on the antenna selector switch will ground all antennas when the station is not in active. A front panel indicator lights when the remote antenna switch motor is running.
