The TXStop function disables the transmitter when it 
is enabled. If TXStop is enabled, pressing the PTT key 
will issue an audible alert tone, indicating that you are 
unable to transmit. Select Menu 45, and set it to ON if 
you would like to enable this feature. The default 
setting is off.   

VOX, or Voice-Operated Transmit, allows you to 
transmit by simply speaking into the microphone. 
With VOX enabled, you won’t need to press the PTT 
key to enable the transmitter. Use Menu 46 to turn 
VOX ON or OFF. The default is OFF.   
VOX S (Sensitivity):
VOX Sensitivity determines the level of sound that is 
needed for the VOX to key the transmitter. You should 
experiment with VOX Sensitivity to find a level that 
is appropriate to your voice but does not trigger on the 
presence of too much other background noise. Set Vox 
S using Menu 47. There are eight possible levels. The 
default level is 3. 
VOX D(Delay): 
VOX Delay determines the delay to stop transmitting 
after you finish speaking. Set the VOX Delay in Menu 
48. Too short a delay will cause the transmitter to
