One more bit of feedback. I have noticed that if an external speaker/mic is plugged into the radio while it is on the audio on DMR stops working. The menu beeps and other radio alert tones stops working as well. The analog audio continues to work fine even transmitting. If I try and transmit to the parrot DMR talk group I don't get any response. If the radio is powered off before plugging in the speaker/mic then power it up all works as expected while the speaker/mic is plugged in.
