A simplified way to make it work would be to take out all cards. Modify the
station control per Kevins info in repeater builders. Find the Ptt of the
transmitter and run to the station control board. I have modified 2 this way
and they both work great. I use a separate micor sq chip but you can use the
one in the Rx per repeater builder info.

Well, the MICOR Community Repeater manual supplement arrived today, and I've
been going through it with the proverbial fine-toothed comb.
I replaced most of the jumpers I originally removed from the backplane.
(According to the jumper matrix in the CR manual, they needed to be IN
whereas the "regular" repeater indicated they needed to be OUT.) I also
went through the various cards necessary and checked jumper settings for
those. This is where I ran into my next problem(s).
First off, the repeater does NOT need a Line Driver card for Community
Repeater operation. I does need:
Time Out Timer
Station Control
Squelch Gate
Master Decoder and
4-User Control modules.
I went through the manual to set the jumpers as necessary, but ran into a
snag with the Squelch Gate. Both manuals ("Community Repeater" and "Control
and Applications") identify the Squelch Gate card as TLN4662A. I have about
a dozen SG cards and they're all TLN8772A, of various vintage. Parts are
laid out differently than what is shown in the manuals, and I can't even
find some of the jumpers referenced in the manuals on the cards.
Specifically, I can't seem to find JU-12, JU-14 or JU-15... if they're on
the card, they aren't very marked well.
Anyway, I've actually take a step backward with this project, in that once I
replaced the jumpers on the backplane, I lost repeater operation with the
Line Driver card. (In a way, I kind of expected that, though.) I was able
before to key the repeater with the proper input freq and PL, now I cannot.
Also if I key the station with the PTT switch on the Station Control card,
it does not drop when PTT is released.
My first question is: Is there a different version of the Squelch Gate card
that I need, or is the TLN8772A a "direct replacement"? If it is a direct
replacement card, does anyone have the manual page(s) for this particular
card so I can get the jumper settings and locations picked out? My thinking
at the moment is that I still don't have the jumper configuration correct on
the SG card...
Next, the manual calls out yet a different part number for the backplane:
TCN1211A. To reiterate, my backplane is a TRN6421A.
I'm getting more confused as time goes on. If Motorola issued
upgrades/revisions for the various control cards and the backplane, the
documentation isn't contained in any of the manuals I have. My backplane is
apparently properly labeled for card placement (according to the Community
Repeater manual) but for whatever reason, I'm not making any progress.
