Radioddity GM-30 Low TX Audio?


Recommended Posts

I am considering purchasing a Radioddity GM-30 GMRS HT.  Of the various negative comments made in reviews, one that is disconcerting is reports of low TX audio.

Commentators have said "you need to practically eat the mic to use it" or "if you're more than an inch away from the mic  TX audio is nonexistent."  Purchasers, including some on this forum, have returned the radio for this reason.

For the folks on this forum, especially if you own a GM-30 and have used it for some time, what is your assessment of its TX audio?  Thanks.

No one has responded to you yet, but I have the clone Pofung P15UV and have no such reports.

Any many here have lauded the GM-30 for its features set vs. price and again, I do not remember any such criticism.

Try one where you can return it if unhappy and see for yourself!

First, thanks everyone for your responses.

Regarding making sure that the radio was in wideband mode, some of the reviewers had stated there was low tx audio even after verifying the radio was set to wideband.

Perhaps the people who reported low tx audio happened to get an affected model.  I don't remember if it was here, on Amazon, on RadioReference, or a comment in a Youtube review...someone thought a possible explanation could be that remnant flashing from the manufacturing process maybe blocked the mic partially.

It's been awhile since the GM-30 was introduced.  If there was a manufacturing issue, maybe Radioddity addressed it.  If so, they didn't let on in their response to my email in which I asked if they were aware of reports of low tx audio.

Again, thanks for everyone's responses.

Did they ascertain that both radios were set to wide band mode?

I bought two Radioddity GM-30 HT's about a month apart from one another.

One has normal tx audio, the other has low tx audio -- need to talk very close to microphone. Same firmware version, same programming, same band width (wide/narrow).

I think the low audio started happening about a month after I bought it, I recall it being fine when new from the box.
