In my car I have a pair of XTL’s. One on UHF, & one on 900 MHz. Both radios use RMN5053 mikes which were made for the XPR DMR radios. But people tell me my TX audio sounds better with them vs the proper XTL mike. Plus they have two buttons on the side, & on both radios, I use one button for talk around. Whenever I start the car, & both radios fire up, the UHF radio gives a boop like an invalid button was pushed. The 900 radio does not do this. But if I unplug the mike, & tuen the radio on, there is no boop. But if I plug the mike in after the radio is on, I still get the boop. Swapped mikes, & no difference. The 900 radio is fine, but the UHF isn’t. Other than that, the UHF radio works fine. Just when it’s fired up, & I hear the boop. Both radios have recent FW. Anyone seen this before?
