20.6.2 ANTI-TRIP VOX
Signals from the speaker(s) might trigger or trip the VOX
unintentionally. VOX ANTI-TRIP will counteract this. Adjust
to get both reliable action and anti-trip of VOX circuit.
20.6.3 Hold Time VOX DELAY
DELAY of VOX circuit allows adjusting the hold time of
VOX activation hence to get smooth VOX operation and
to counteract any VOX switching between fluently spoken
voice.
20.7 Monitoring TX Signal MONITOR
Turning the MONITOR control will adjust the volume of
the audio to monitor the transmission of PT-8000A
(avoiding acoustic feedback). Setting control fully counter
clockwise for terminate MONITOR function.
20.8 Fall Time TX for CW TX-DELAY
Turning TX-DELAY will impact the time for transmit-receive
switching (turn-around time) during CW mode. Setting
TX-Delay fully counter clockwise ensures the shortest T/R
turn-around possible – called BK (break in).
Turning TX-DELAY clockwise will increase the turn-around which allows
alignment to individual CW habits.
