TRANSMITTING VOX (VOICE-OPERATED TRANSMIT) VOX eliminates the necessity of manually switching to the transmit mode each time you want to transmit. The transceiver automatically switches to transmit when the VOX circuitry senses that you have begun speaking into the microphone. When using VOX, develop the habit of pausing between thoughts to let the transceiver drop back to receive briefly. You will then hear if anybody wants to interrupt, plus you will have a short period to gather your thoughts before speaking again. Your listener will appreciate your consideration as well as respect your more articulate conversation. VOX can be switched ON and OFF independently for CW and the other modes excluding FSK. Press [VOX] to toggle VOX between ON and OFF. • "VOX" appears when the function is ON. ■ Microphone Input Level To enjoy the VOX function, take time to set the gain of the VOX circuit to the correct level.

TRANSMITTING
VOX (VOICE-OPERATED TRANSMIT)
VOX eliminates the necessity of manually switching to
the transmit mode each time you want to transmit.
The
transceiver automatically switches to transmit when the
VOX circuitry senses that you have begun speaking into
the microphone.
When using VOX, develop the habit of pausing between
thoughts to let the transceiver drop back to receive
briefly.
You will then hear if anybody wants to interrupt,
plus you will have a short period to gather your thoughts
before speaking again.
Your listener will appreciate
your consideration as well as respect your more
articulate conversation.
VOX can be switched ON and OFF independently for
CW and the other modes excluding FSK.
Press
[VOX]
to toggle VOX between ON and OFF.

Microphone Input Level
To enjoy the VOX function, take time to set the gain
of the VOX circuit to the correct level.
This level
controls the capability of the VOX circuit to detect the
presence or absence of your voice.
When using CW
mode, this level cannot be adjusted.
