I'm buffalo'd  (not unusual for me).  Got a UHF (462 mhz) unified 
micor...was working fine a couple of weeks ago...it's just been 
siting in my office unplugged.  I finally got around to tuning the 
duplexer today and when I connected everything back up...nuttin.  I 
can't key up using the station control switch.  When bypassing the 
PA, and hooked the exciter (low level amp out) to the watt meter (5w 
slug), there is no reading when the station is keyed, turned on or 
off, or when I key it up with my hand held.  On my service monitor, 
I can pass the pl tone to the repeater and hear it through my 
handheld on the repeater output freq.  There is no external 
controller on this by the way.  I plugged in the test set and here 
are the readings...

switch 1...0
switch 2...26
switch 3...36
switch 4...32
switch 5...starts out at 10 when the unit is cold and then drops to 4


Again, when the unit is keyed, nothing changes.  My hand held picks 
up a signal also when the unit is just sitting there.  If I key my 
handheld, I can hear a squelch tail.  The exciter gets fairly warm 
too.  Any ideas?

Thanks
