Hi,
Can you pls add a few more details:
1. are the 2.5mm jacks stereo (3 pins) or mono (2 pins):
2. is your universal headset monaural or stereo; and
3. originally, did the universal headset came with 2 separate plugs?
At most that I can give you is a general/generic idea. The external
speaker/microphone (or in your case the universal headset) uses also
the charge jack, chances are that it is a multi terminal/pin jack. Pls
refer to the diagram below.
The reason it is in continuous transmit is because one of the mini
speaker is wired to the PTT trigger or the pins are wired wrong;
This would also explain why no transmit audio either manual or via VOX.
Hope this be of some help/idea. Post back how things turned up or should you need additional information.
Good luck and kind regards.
