TRANSMISSION

VOX (VOICE-OPERATED TRANSMISSION)

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 VOX 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.
Press [VOX (LEV)] to toggle between VOX ON and
OFF.
• " " appears when the VOX function is ON.

Microphone Input Level

To enjoy the VOX function, take the time to
properly adjust the VOX gain. This level controls
the capability of VOX 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 (LEV)] to switch the VOX function
ON.
• " " appears.
3 Press and hold [VOX (LEV)].
• 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/CH 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 (LEV)] to switch the VOX function ON.
• " " appears.
3 Press and hold [KEY (DELAY)].
• 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/CH 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 [CLR] to store the parameter and exit the
setting mode.

Anti-VOX Adjustment

The TS-590S transceiver has a DSP IC to improve
and customize incoming/ outgoing audio signals.
When the 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.
Note: When connecting a headphone to the Phone jack,
Anti-VOX will not function.
■

Data VOX

Although the microphone is normally used for
VOX transmission, you can also utilize the audio
input of the ACC2 or USB connector. When the
transceiver detects an audio signal on the ACC2
or USB connector, it automatically transmits.
You can select ACC2 or USB via Menu No. 63
("Selecting a Data Transmission Line") {page 58}.
1 Select USB, LSB, FM, or AM mode.
2 Press [MENU], then press [Q-M.IN]/ [Q-MR] or
turn the MULTI/CH control to select Menu No.
69.
3 Press [M.IN] to set the VOX with DATA input
function ON.
4 If necessary, adjust the VOX gain level for the
ACC2 or USB connector {page 31}.
Note: While VOX with DATA input is set to ON (Menu No.
69), speaking into the microphone also activates the VOX
function and you can still transmit using Mic [PTT]. Anti-
VOX does not function with Data VOX.
While the Data VOX function remains ON and the
transceiver is connected to a sound source, such as a PC,
the transceiver may begin transmitting due to the sounds
emitted from the sound source. To avoid unintended
transmission while the transceiver is connected to the
sound source, turn the Data VOX function OFF.
