Hi, Jeff - and thanks for the quick reply.
The number on the backplane does NOT match - but don't ask me what it is,
because I'm at work and can't get to the station right now. I should be
home by 3PM CDT, so I can post it then if necessary. I do know these were
repeater station originally, not paging stations.
So how do I go about getting the proper documentation? I'm pretty sure the
manuals are all out of print by now... (I do have the "orange book" -
Applications Manual, I think - as well as the manuals for both the low and
high power stations.) However, the orange book does not show all the
modules I have - I know it doesn't cover the 4-User Control Module, and
maybe not the Master Decoder either... I have several versions of the
Station Control, Squelch Gate and Time Out Timer modules - some schematics
for the "newer" revisions are not shown in the manual either.

Could be quite a few reasons why you don't have repeat audio. Start at the
receiver and work your way forward, using the chart for the unified chassis
and the module schematics in the "orange book" to help you follow the repeat
audio path through the station.

You sure you have a standard backplane? There were a number of varients,
one of the more common being the backplanes that were used for Micor PURC
(paging) stations. Check the part number stamped on the backplane board for
the unified chassis and make sure it matches what you have documentation
for.
