Everyone, today I tried contacting Motorola parts for a manual and/or
schematic for the Master Decoder module I have, Part #TLN5803A.
Needless to say, navigating Motorola's call-handling system was a real trip.
First I ended up with someone in Cell Phones, then someone in
Recreational Radio. I
Are you sure you have the encode board plugged in with a reed plugged in?

The station is a Community Repeater - not the conventional MICOR repeater
that most are familiar with. In other words, it uses a different backplane
and different card configuration than a regular repeater. The primary PL
card is called a Four User Control Module and can have up to
A community repeater has NO PL Encoder..
The PL from the receiver is decoded and the PL tone is low pass
filtered and passed to the transmitter PL Encode input by the Master
Decoder card in the station.
So, if you key the station locally there is NO PL Encode.
Also, there is NO PL tone on the

I am keying the repeater with an external source (AKA: HT) that is encoding

The Master Control module is NOT passing PL to the modulator on Pin 2. THIS
is my problem. I need a schematic for the Master Control module that I have

Right-mine is similar. I re-purposed the PL disable transistor to
function as the F1 channel element enable

Well, changing out the backplane got the repeater working... along with
double-checking the jumper settings one the cards.
I did find a couple of jumpers that needed to come out on the Station
Control card, and I'm sure that helped.
The machine still does not pass audio, so now that it is

Mark,
OK, now back to where we started from, but much better.
I have a bunch of questions for you.
1. Do you have a local speaker hooked up? If so do you have audio out
of the speaker in either carrier squelch or PL mode?
2. Do you have repeat audio in carrier squelch mode? I know you do not

Mark,
Sorry to hear you are still having problems. The Micor series of
radios were made for many years and yes, there were several variations
of most every module made. That is one of the reasons that there was a
complete manual set delivered with each radio.
Without a whole drawer full of
Hi, Joe.
Yep, unfortunately they reference the same modules in both manuals. And I
am trying to configure the jumpers for a non-wireline RT station.
I wonder if I may have screwed something up when I took most of the jumpers
out of the backplane (all except JU-5) and them put them back. Since
Mark,
I think you have a good idea about starting fresh with an unaltered
board.
That would be my next move. It could not hurt to grab another set of
cards also. These are old enough that I have found some bad caps and
a bad transistor or two when going through my extra cards.
What I will
Mark,
It sounds like you may be missing the modifications on the
interconnect boards for and squelch. If the audio/squelch board has
been modified for and squelch and the interconnct board changes have
not been made, you will have repeat audio in PL Disable or carrier
squelch mode and no repeat
Thanks Joe!
Like I wrote earlier, it appears I'm going to have problems finding the
Community Repeater supplement... If you can help me with that, I'd be much
obliged!
I actually have several 4-User Control cards and more tone reeds, so I could
potentially have up to maybe 10 or 12 PL codes
if that is the case
good luck.

Pull the exciter board out and measure the resistance between pins
one and five on the transmitter interconnect board. There should be
infinite resistance between the two pins. If there is continuity

Mark,
I agree with Eric, you are aways away from cutting and hacking on
traces until we can identify exactly which backplane board you are
working with.
Most of the time that I have seen the TRN prefix, it usually has been
tied to the PURC series of radios. Are all of your backplane boards
that
Mark,
I think Eric is correct in that you have got a community repeater
chassis. These can be a handful to get properly jumpered and
configured. If you can not find a TLN5644A backplane board, this will
be a little more of a challenge.
I think you are in a holding pattern here until your
