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.

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. > Besides, the manual's diagram for the backplane shows jumpers > numbered in a > certain sequence and the backplane I have has them numbered > differently - > they're in the same locations, but numbered differently. 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. --- Jeff WN3A ------------------------------------ Yahoo!
