The Station Control unit

The station control deck controls turns on plate and filament voltages, switches transmitter on and off the air. The meter indicates the line voltage. The power supply on the control deck furnishes voltages to the speech amplifier. A schematic will be added in the future.
Below are two views of the rear of the station control module. Rear view of station control, 2 prong sockets for 120 volts switched by front panel switches to transformers on other decks. Seven pin socket is for cable to speech amp. Large rotary switch switches voltages to either the VHF deck or the HF deck.
Power supply with 5Z3 rectifier is for the speech amplifier. The speech amp power supply is on the station control chassis.(visible in lower right photo)
