    As long as you are getting audio to the radio, so when you key up using PTT and there is audio showing in the transmition then vox should work.
    Are you seeing good audio reflection on the audio meter?
    Make sure vox is turned on and keep moving the vox slider till it triggers as you talk.

    Maybe this will help.


    Make sure the bias is off and the headset is not an IC for Icom radios.
