the transceiver. Fixed frequency operation is convenient for operation on often used frequencies. The fixed channel os- cillator replaces the VFO when the FUNCTION switch is pla- ced in the FIX position.

@DRIVE KNOB

The DRIVE tuning control tunes the plate tank circuit of the 12BY7A driver as well as receiver's antenna and mixer coils. In receive the DRIVE control is tuned for maximum sensitivity lmaximum S-meter deflection). In transmit the DRIVE control 1s tuned for a maximum ALC reading. When the control is correctly tuned for transmission it will be cor- rectly tuned for reception.

@PLATE KNOB

The PLATE control adjusts tlie plate tuning of the two final ampl~fiertubes.
