I just installed a Becker AR4201 that I picked up used from the UK (frequency spacing change from 25 to 8.33). I have it paired with a Peiker TM 170 I got from W&W based on their compatibility statements on the website. It will transmit voice, but it is extremely soft/quite and the receiver needs to have the volume all the way up to hear it. Does anyone know what the problem is and how to fix it? I did a search but didn't come up with any answers. Thanks.

Try adjusting the mic sensitivity setting SF16 using service mode. See pages 3-11 and 3-16 of this manual (Thanks, Cumulus Soaring!)

Thanks Bob. This looks really promising. I'll give it a try this evening.
