I have yet to find any type of relatively complex software driven uP in controller operation that didn't freeze or fart (lock) up at some point in time. One would hope the mfgr hopefully included some type of "dead-man" or equivalent software-hardware reset timer. > > Years ago Comm Spec supplied a small board that reset power > > to the controller to eliminate the problem.

Q: The repeater hardware (radios)? the Zetron Controller? both?

A received signal should indicate on both the RX Radio and the Zetron front panels. The Zetron should indicate valid tone/dcs codes and the Tx activity should be indicated on both the Zetron and TX Radio front panels. Step two depends on the answer(s) to the above question. s.
