TRANSMITTING
VOX (VOICE-OPERATED TRANSMIT)
VOX eliminates the necessity of manually switching to
the transmit mode each time that 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, get into 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.
Press [VOX] to toggle the VOX function ON or OFF.
• “VOX” lights when the function is ON.
■ Microphone Input Level Adjustment
To enjoy the VOX mode, take time to set the gain of
the VOX circuit to the correct level.
1 Select a voice mode, switch ON the VOX
function, and begin speaking into your
microphone using your normal level of voice.
2 Access Menu No. 28 (VOX.GAIN), then select
different settings (default is 4) until the transceiver
reliably switches to transmit each time you speak.
• The best setting will allow the transceiver to
switch between receive and transmit;
however, background noises near your
operating position should not falsely switch
the transceiver.
• This Menu item is configurable even if the
VOX function is OFF or while you are
transmitting.
Note: This transceiver does not have an ANTI-VOX control. DSP is
able to automatically lower the input sensitivity for received audio that
is output from the speaker.
■ Delay Time Adjustment
1 Select a voice mode, switch ON the VOX
function, and begin speaking into your
microphone using your normal level of voice.
2 Adjust the DELAY control so that the transceiver
changes back to receive a brief time after you
stop talking.
• The DELAY control has a range from
150 ~ 2700 ms. Each step equals 10.6 ms.
Note: Setting the delay time by computer overrides any setting
of the DELAY control. The control then has no effect. To restore
functionality to the DELAY control, turn the control. The newly
selected setting becomes effective.
TRANSMIT INHIBIT
Transmit Inhibit prevents the transceiver from being
placed in the transmit mode. No signals can be
transmitted if this function is ON. When the transceiver
is inhibited from transmitting, the graduations on the
PWR meter go out as a visual reminder.
• TX Inhibit OFF: Transmissions are possible.
• TX Inhibit ON: Transmissions are not possible.
Switch the function ON or OFF via Menu No. 27
(TX INH). The default is OFF.
XIT (TRANSMIT INCREMENTAL TUNING)
Similar to RIT, XIT provides the ability to change your
transmit frequency by ±9.99 kHz in steps of 10 Hz
without changing your receive frequency. If the Fine
Tuning ([FINE]) function is ON, the step size is 1 Hz.
1 Press [XIT].
• “XIT” and the XIT frequency display appear.
2 Press [CLEAR] to reset, if required, the XIT offset
to 0.
3 Turn the RIT/XIT control to change your transmit
frequency.
4 To cancel the XIT function, press [XIT].
Note: The frequency shift set by the RIT/XIT control is also used by
the RIT function. Therefore, changing or clearing the XIT frequency
also affects the RIT frequency.
