TRANSMISSION
VOX (VOICE-OPERATED TRANSMIT)
VOX eliminates the necessity of manually switching
to the transmission mode each time you want to
transmit. The transceiver automatically switches to
transmission mode when the VOX circuitry senses
that you have begun speaking into the microphone.
When using VOX, develop the habit of pausing
between thoughts to allow the transceiver to drop
back to reception mode 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 listeners 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/ 8] to toggle between VOX ON and OFF.
• “VOX” appears when the VOX function is ON.
■ Microphone Input Level
To enjoy the VOX function, take the time to
properly adjust the gain of the VOX circuit. This
level controls the capability of the VOX circuit to
detect the presence or absence of your voice.
In CW mode, this level cannot be adjusted.
1 Select USB, LSB, FM, or AM mode.
2 Press [VOX/ 8] to switch the VOX function ON.
• “VOX” appears.
3 Press [VOX/ 8] (1 s).
• The current VOX gain level appears on the
sub-display.
4 While speaking into the microphone using your
normal tone of voice, adjust the setting (default
is 4) using the MULTI control until the
transceiver reliably switches to transmission
mode each time you speak.
• The selectable gain range is from 0 to 9.
• The setting should not allow background
noise to switch the transceiver to transmit
mode.
Note:
The VOX gain level can be adjusted even if VOX is
switched OFF or while you are transmitting.
■ Delay Time
If the transceiver returns to reception mode too
quickly after you stop speaking, your final word
may not be transmitted. To avoid this, select an
appropriate delay time that allows all of your
words to be transmitted without an overly long
delay after you stop speaking.
1 Select USB, LSB, FM, or AM mode.
2 Press [VOX/ 8] to switch the VOX function ON.
• “VOX” appears.
3 Press [KEY/ DELAY] (1 s).
• The current setting appears on the sub-
display. The default is 50 (1500 ms).
4 While speaking into the microphone using your
normal tone of voice, turn the MULTI control
such that the transceiver switches to reception
mode after you have stopped talking.
• The selectable range is from 5 to 100
(150 ms to 3000 ms) in steps of 5, or OFF.
5 Press [MTR/ CLR] to store the parameter and
exit the setting mode.
■ Anti-VOX adjustment
The TS-480 transceiver has a DSP IC to improve
and customize incoming/ outgoing audio signals.
When VOX function is turned ON, the DSP IC
adjusts the Anti-VOX level automatically,
comparing the reception sound level and
microphone input level. So, you never have to
worry about adjusting the anti-VOX level.
■ VOX Source
Although microphone is normally used to perform
the VOX transmission, you can also utilize AF
input of the DATA connector (pin 1) on the TX/ RX
unit {page 78}. When the transceiver detects the
audio signal on the pin 1 of DATA connector, the
transceiver automatically transmits.
1 Select USB, LSB, FM, or AM mode.
2 Press [VOX/ 8] to switch the VOX function ON.
• “VOX” appears.
3 Press [MENU/ F.LOCK] and turn MULTI
control to select Menu No. 60.
4 Press [ ] to switch the VOX with DATA input
function ON.
5 Turn MULTI control to select Menu No. 46.
6 While sending AF signal to pin 1 of DATA
connector, adjust the value (default is 4) using
[ ]/ [ ] until the transceiver reliably switches
to transmit mode each time you send AF signal
to pin 1 of DATA connector.
Note:
VOX function does not work even if you speak into the
microphone. However, you can transmit with the Mic
[PTT]
