station is still transmitting. 

 
039 GEnE ANTIVOX 
Function: Adjusts the Anti-VOX Trip Gain which is the level of negative feedback of 
receiver audio to the microphone, to prevent receiver audio from activating the 
transmitter (via the microphone) during VOX operation. 
Available Values: 0 ~ 100 
Default Setting: 50 
 
040 GEnE FRQ ADJ 
Function: Adjusts the reference oscillator. 
Available Values: –25 ~ 0 ~ +25 
Default Setting: 0 
Connect the 50-Ohm dummy load and frequency counter to the antenna jack; adjust 
the [SUB VFO-B] knob so that the frequency counter reading is same as the VFO 
frequency while pressing the PTT switch. 
Advice: Do not perform this Menu item unless you have a high-performance frequency 
counter. Perform this Menu item after aging the transceiver and frequency counter 
sufficiently (at least 30 minutes).
