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 briefl y.  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.

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.

■

 

If the transceiver returns to reception mode too 
quickly after you stop speaking, your fi nal 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.

The TS-590SG 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.

■

 

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. 69 (“Selecting a 
Data Transmission Line”) {page 61}.

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. 
76.

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 32}.

Note: While VOX with DATA input is set to ON (Menu No. 
76), 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.
