Hi,
Just recently I got problem with 5pin united star mbitr.
Receiving the audio is good and perfect, when I push PTT to send it starts sending ok but when i speak to mic it shatters the audio, sometimes 1/20 audio is ok but usually it is distorted.
I am using the small regular antenna.
I have tried different frequenzes PMR.
I have tried with headset*, and without headset, same effect.
Battery has been charged /rebooted.
It has not been reprogrammed since it worked.
*ptt:s, nexus u94 and tci liberator.
headset comtac 1 with z-tactical microphone bar.
This set worked fine for 5months.
Has anyone encountered problem described ?
