@ MONITOR GAIN CONTROL [MONI GAIN] (p. 35)
Varies the volume of CW sidetone, optional voice
synthesizer and monitor output (when [MONITOR]
is pushed IN).
@ MIC TONE CONTROL [MIC TONE]
_ Adjusts the transmit audio response.
@ ANTI-VOX CONTROL [ANTI-VOX] (p. 36)
Adjusts the VOX deactivate level to prevent
unwanted VOX control from the speaker audio.
@ VOX GAIN CONTROL [VOX-GAIN] (p. 36)
Adjusts the transmit/receive switching threshold
level for VOX operation.
®© VOX SWITCH [VOX] (p. 36)
Turns the VOX function for phone (SSB, AM and `
FM) operation ON and OFF.
FUNCTION
The VOX function (voice operated transmission) starts
transmission without pushing the transmit switch or PTT
switch when you speak into the microphone; then,
automatically returns to receive when you stop speaking.
@ MONITOR SWITCH [MONITOR] (p. 35)
Monitors your transmitted IF signal.
- The CW sidetone functions when [MONITOR] is OFF
in CW mode.
@ SPEECH SWITCH [SPEECH] (p. 44)
Announces the MAIN readout* frequency when
an optional UT-66 is installed.
* SUB readout freq. when pushed together with [XFC].

FUNCTION
The speech compressor compresses the transmitter
audio input to increase the average audio output level.
Therefore, talk power is increased. This function is
effective for long distance communication or when
propagation conditions are poor.
