Multimeter: Indicates plate voltage, grid current, and forward or reflected watts as selected by

meter switches

(8).

Plate Current Meter: Indicates plate current.

3. Indicator Lamps: Indicate standby or operate condition,

SSB (high power) mode, and multimeter

function.

STBY Switch: When depressed, allows standby operation with the exciter connected straight

through to the antenna.

AGC Control: Adjusts the transmitting AGC threshold.

ON/OFF Switch: Turns the main power on and off.

MODE Switch: Selects highplate voltage for SSBoperation or lowplate voltage for CWoperation

oi for tuning.

Meter Switches: Select indication for Multimeter (1).

PLATE Control: Resonates the plate tank circuit.

10.

BAND Switch: Selects input andplate tank components to resonate the amplifier on the selected

band.

11.

LOAD Control: Adjusts the output impedance of the amplifier to match the antenna load
