One of my 900 MHz PURC5000 manuals has several Micor receivers in it, including
72 MHz. There's also a section that seems to cover the chassis, although I
don't know if it's the same one you have. It might be. One board has a squelch
pot and an RJ45 jack on it. If that's mounted directly behind the front panel,
then it just could be the same board. There's also room inside the chassis for
a DPL decoder board and a flat audio board. I suspect these same modules would
fit into a SpectraTAC chassis but I haven't checked the pinouts.
There's a ribbon cable from the main interface board to the rear panel. The
schematic shows the pinout of that connector. Nothing magic but the flat cable
does make a mess of the various signals.
I would expect you could put ANY wide-band Micor receiver into the unit and it
would work just fine. I don't know how the unit interfaces with the parent
station, but obviously it can be done.
I thought I had a full manual for that exact chassis. I still might; just
haven't come across it yet.
