|Table 2-2 KWM-2/2A Operating Control Functions (cont).|
|VOX GAIN (R39)||Controls gain of VOX amplifier for voice-controlled operation|
|VOX Time C0NSTANT (R 43)||Controls hold-In time of VOX circuit.|
|INCR LOAD)||Adjusts power amplifier output Impedance level to match transmission line Impedance: for maximum power transfer.|
|Zero set knob||permits calibration of frequency dial.|
|Vfo tuning dial||Selects the frequency to be added to the band frequency to establish the transceiver operating frequency.|
|*These operating controls are inside the cabinet.|
During amateur operation. DO NOT operate transmit circuits while the transceiver is tuned to receive outside the amateur band in use. The transmit frequency is always locked to the reeeive frequency Return tuning to within the band before transmitting.
2.4 TRANSMITTER TUNING
TO PREVENT DESTROYING THE FINALAMPLIFIER THE FOLLOWING STEPS MUST BE MADE QUICKLY.
If the operating frequency is changed more than 50 kHz recheck tuning and loading adjustments. Readjust if necessary.
