TOPIC:

I have always used VOX for SSB contests. Having problem getting my new PGXL and my new K4 to work in SSB VOX. Very intermittent. Might work on first voice input but then the second I get "RF DETECTED 10MS AFTER PTT". Been playing with any setting I can find that has to do with VOX but not making any progress.

Hi, please refer to page 59 of K4 operations manual and adjust VOX Delay accordingly. Values between 20 and 40 ms should be OK.
