Mystery: "Repeater Problem of the Month Club".
I just repaired a problem with our 224 Mhz
Repeater System. Let's see how you fair with
a guess?
Symptom: Repeater audio would fail, not pass
the receiver to the transmitter. Controller CW
and speech audio ok.
Initial Service: Missing Repeat Audio would return
after re-seating the Link RLC-6 Audio Board chips.
The repeater would run fine for 1-3 days before the
problem returned (missing repeat audio)
Second Service: Replaced the RLC-6 board and
firmware, returned the repeater to service.
Lasted 1 week before the audio again failed.
2nd Symptom: Arrived to find the main Controller
locked in a quasi reseting fault mode. Replaced
the controller with a spare. Unit lasted about
3 days same problems return.
3rd Trip: Replaced entire Repeater RF deck and Link
RLC-6 Board with spare (different brand and model)
Repeater. Controller is still the replaced 2nd unit.
Everything bench tested for 2 days at the shop.
Unit failed after 1 day back at the site.
X-Number Service Call: Found 2nd Controller in
loop fault reset problem (same as the first).
All supply power normal, the same supply operates
three other repeaters in the same rack. At this point,
the entire repeater had been swapped out for spares
and the DC Power Supply tests and works normal
(operated no where near its max capacity). Stand
back and scratch your head, then tell me what you
would do now?

I found the problem, care to guess what it was?
