I am dealing with a similar problem with a Mastr II and a NHRC controller.
The audio sometimes fades out dropping to a very low level, and changes
while you are listening to it on a repeater user, although it comes back
all by itself. It seems to be an analog problem as opposed to just cutting
out all together... I am suspecting ( and working on correcting by parts
changes) that it is a bad cap in line or reverse bias on a cap or such. The
coupling caps are polarized and mic high has a bias on it, and if the
potential get reverse of the coupling caps I think it may be the issue.. I
thought I had it solved but it came back and then has been gone for a
couple weeks.. Next suspect is the audio hybrid on the exciter or maybe a
cap in the audio circuits...
Food for thought anyhow...
