I recently purchased a PMMN4025A to upgrade from my 4024A. After updating my CPS configuration, I noticed that when connecting it to my 7550e, there was almost no sound from the 4025 unless I offset the radio to +20dB and cranked the volume up. The mic and emergency button still function as normal, and I still can hear transmissions - it’s just not anywhere near being loud enough to be usable.
Connecting my 4024 works as normal, but for some reason the 4025 doesn’t work on my 7550e, but it works fine on my 6550. Funny enough, I had almost the opposite problem on my 6550, where I couldn’t get the PTT tone to go above a certain volume with the 4024, but it works fine with the 4025.
I tried rolling back the config on my 7550e, but with no luck. My best guess would be a connector issue on my 7550, but I’m not sure why it would still function otherwise but not at a usable volume. Any help is appreciated.
