XG-100P Audio Quality - Mods / Tweaks

[W4UO]

Is there any adjustment or mod to the hardware possible for analog audio? I know that any adjustment on this I believe is when hooked up to service monitor for alignment. I was curious if anyone had any tricks or thoughts?

Maybe a waterproof membrane over the mic elements to remove.

There is mic gain, AGC and noise canceling. In my experience noise canceling can negatively affect transmit audio quality and you have to play with mic gain and or AGC to your liking. All of this should be in RPM under options then audio settings.

Does the agc affect the analog audio as well? I see where it says for p25 audio.

I don’t have RPM open but I think there are AGC options for analog. If I have time I’ll see how my radios are programmed and post here.

Thanks. I know the radios are wideband enabled.

Just checked one of my radios and internal mic gain is 9dB, seems a little high and external mic is 3dB. No ALC. People seem to like the sound and I don’t operate in very noisy places. You might try that as a starting point and adjust with someone who knows your voice listening on a radio with good audio.

Good idea. Did you notice the agc setting?

No AGC, no ALC. But you should test with them on and off so you know how they will impact the sound.

Under General Options you also have noise cancellation type A and B. If you try NC don’t forget to try both options.

I will give it a shot and report back. The reports that I get back is a hollow/distant sound currently. Though I keep my mouth close to the mic.

That is the NC, turn it off. I have ALC on which gives me the option to turn it on and off via the menu. NC is designed to suppress siren noise, and doesn't work so well in a quiet environment.

Edit: I have both gains at 0db

Where in the menu would you enable or disable ALC in radio menu, do not see it under audio? I turned it on in the under audio options in the programming software.

Also , oddly enough , I tried 3db for speaker mic and 9db for the internal mic. ALC off. NC is off. Audio was reported to be low, not unintelligable but lower than whats normal for me. This was tested analog VHF and UHF. Now to remedy this I had to goto 12 to get decent audio.

Was the radio re-housed? I had heard a while back that this could be a symptom of a rubber gasket not being installed/reinstalled on (I believe it's) the rear mic.

Possible, I'll have to check. I see it's still has the white sticker over the single screw under the plastic cover then I'll have a fair idea.

XG100P unity or any Harris device for that fact does not give you all the specific audio equalizer options like Motorola does… essentially you’re stuck with what you have
