A63 ALC Board (Schematic 10051819,10051526) 

This section describes the operation of the level control board.  The level control board performs the following 

functions: 

•

 

Provides automatic level control of the amplifier’s output when the amplifier is placed in the ALC mode. 

•

 

Limits RF input level to the amplifier and turns on the audio alarm when forward or reflected power levels 

exceed specified levels. 

•

 

Drives forward and reflected indicators on the front panel display.
