I have a strange problem with the VOX operation with my ICOM 706 MKII, and wanted to know other peoples experiences.

I use a headphone with microphone. I start talking and adjust the VOX gain until the rig goes in to transmit. When I stop talking, it goes to receive for just a couple of milliseconds and goes back to transmit for the duration of the VOX delay. And this keeps repeating until I turn the VOX gain back down on the side of the ICOM.

The anti-vox does not help, and anyway, the mic does not pick up any noise from the speaker since I'm using headphones.

I suspect that the click of the relay, switching of the transmit, triggers the trx to go back into transmit.

Did anybody else succesfully used the VOX on this model? Am I doing something wrong?

Sounds to me like an "anti-vox"  adjustment promblem, look in the manual

Sounds like either you have the headset mis-wired and are electrically feeding back some of the headphone audio to the mike,   or else there is enough acoustic cooupling in the headset assembly to couple some audio directly.
