The old controller was actually having problems opening up when the radio went into receive. So it's a bit different. I am trying to get my hands on another controller to see if that helps. Also may try putting the old controller back in to see if it starts working any better.

If so, it's probably something wrong in the MastrII radio. I would troubleshoot this by taking the covers off of everything so that I can access several points in the transmit audio chain. I'd take some audio readings with the repeater working correctly, then wait until the trouble happens and see what changed. At least this will point you to the area where the trouble is occurring. As I wild guess, I would suspect a bad capacitor. With MastrII boards being so easy to get, I would probably just change out the board. 73, Joe, K1ike Vernon Densler wrote: > > > Here is my setup.
