I have a VXD-720 (VXD-720-G6-4, 400-to-470 UHF) and have tried a couple of MH-66A7A hand mics with it.
I get audio reports using the hand mic that go from completely unreadable to just marginally terrible on TRBO. One was a brand new out of the box and the other known good used, so I *think* both are electrically OK. Not guaranteed, I know, but my assumption at the moment. Tried trimming the waterproof membrane from one of them and the audio report was that it was still extremely low audio level, so I don't think it's a case of just muted audio due to the submersible feature.
Removing the mic and using the radio's built-in one works fine, high quality audio, no issues. Tried with auto gain on and off, didn't make any difference.
Any pointers as what might be the issue? Hoping it's just a setting some place. I only have the one radio to test with, so I can't say for sure it's not the radio. I got it used and you never know what may have happened in the past. But the radio recognizes the mic, it produces a tone during power up right before received audio starts coming out of the mic speaker (which sounds good) instead of the internal speaker. No other issues with the radio, programs fine, for example.
