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. 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.

1 Select SSB, FM, or AM mode.

2 Switch the VOX function ON.

3 Access Menu No. 16.

4 While speaking into your microphone using your

normal level of voice, select different settings (default is 4) until the transceiver reliably switches to transmit each time you speak.

The selectable range is 0 to 9.

The final selection should not allow background noises near your operating position to falsely switch the transceiver from receive to transmit.

Note: Menu No. 16 is configurable even if VOX is OFF or while you are transmitting.

Delay Time

If the transceiver immediately returns to receive too quickly after you stop speaking, your final word may not be transmitted. To avoid this, select the appropriate delay time that allows all of your words to be transmitted without an overly long delay after you stop speaking.

1 Select SSB, FM, or AM mode.

2 Switch the VOX function ON.

3 Press [DELAY].

The current setting appears. The default is 50.

4While speaking into your microphone using your normal level of voice, adjust the MULTI/CH control such that the transceiver switches to receive a brief time after you stop talking.

The selectable range is 5 to 100 (150 ms to 3000 ms) in steps of 5, and OFF.

5Press [DELAY] again.
