Ssb/Am/Fm Modes - Yaesu FT DX 9000 CONTEST Operation Manual

VOX: A
UTOMATIC
Instead of using the microphone's PTT switch or the front panel [ MOX ] switch to activate the transmitter, the VOX (Voice
Operated TX/RX Control) system provides hands-free, automatic activation of the transmitter, based on voice input into
the microphone. Setup of the VOX system takes only a few seconds.
[ VOX ] Switch
[ VOX ] Knob / [ DELAY ] Knob
1. To start, set the [ DELAY ] and [ VOX ] controls fully
counter-clockwise (to the left).
2. Press the [ VOX ] switch to engage VOX operation.
3. Speak into the microphone in a normal voice level,
and rotate the [ VOX ] knob clockwise (to the right)
until the point where your voice input activates the
transmitter.

DVICE
Do not advance the setting of the [ VOX ] control too
much, because to do so will make the transmitter re-
spond to minor background noises in your station.
4. Now stop speaking, and note the amount of time it
takes for the receiver to recover. If the hang time is
too long or too short; rotate the [ DELAY ] knob, while
speaking briefly into the microphone and then paus-
ing, so as to set the desired hang time. Clockwise rota-
tion of the [ DELAY ] control will increase the hang
time.
5. To exit from VOX operation, press the [ VOX ] switch
once more. We recommend doing this if you are going
to leave your station, to prevent inadvertent activation
of the VOX system by a ringing nearby telephone,
speaker audio from a TV, etc.
