Jeff,
I found that one of the transistors got bent over and had the legs
touching, I bent it back and it worked fine! Oh well, now I have a bunch of
extra cards.

Subject: RE: [Repeater-Builder] Low Band Micor Key probelm
I don't have a control shelf manual ("orange book") here for the Micor, but
one other thing to check is the PL encoder on the transmitter (if it has
one). If the keying transistor or other logic on that board got hosed, it
could "latch on", keeping the transmitter keyed.
