ALC/RF meter switch
ALC meter

(SSB made only}
RF meter
Used to indicate the output power.
PROC (Processor) switch
Effective transmit power output will increase when
the PROC switch is turned ON during USB or LSB
mode operations. (= 4-3-5, Speach Processor)
Note: = -
When the speech processor function is used in the
USB or LSB mode it is possible to overdrive the trans-
mitter. An easy way to check for excessive modula-
tion is to monitor the ALC meter. !f the needle is over
the ALC zone you are overmodulating. Reduce the
MIC gain control setting until the needle remains in
the ALC zone on voice peaks.
