RE: [Repeater-Builder] UHF MICOR Unified Chassis
More information about this project. I have the station working - receiving, decoding proper PL tone, repeating, transmitting audio, etc. The only thing it is NOT doing is encoding tone for transmit. (A reminder - this is a Community Repeater MICOR chassis, NOT the standard repeater chassis.) Anyway - from what I can tell, the Master Control module is NOT sending tone out to the modulator. The problem I have is this: the manual supplement I have shows a different Master Control module that what I have. My modules are not IC-based, the ones on the manual are. Therefore, I believe the schematic and operation for the module I have is completely different than that in the manual. Does anyone have an earlier issue of the Community Repeater manual - 68P81025E55 (probably revision A, since mine is a B)? *ALL* I think I need are the pages pertaining to the Master Control Module - part #TLN5803A. (Other part numbers may be: TLN8780A or TLN1684A - these are numbers stamped on the flange of the card - the first number above was printed right on the circuit board.) The module referenced in my manual is TRN6165A. For those with a manual - I am seeing tone at Pin 7 (Tone PL Out) but not at Pin 2 (Tone or Binary PL to Modulator) on the Master Control module. I tried merely jumpering Pin 7 to Pin 2 - doesn't work. Because the schematic and board layout is completely different, I have no reference to be able to chase signal through the circuit. I'm also wondering if a required jumper is missing or a jumper is improperly installed on my Master Control card. Thanks! Mark - N9WYS
RE: [Repeater-Builder] UHF MICOR Unified Chassis
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.
RE: [Repeater-Builder] UHF MICOR Unified Chassis
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.

RE: [Repeater-Builder] UHF MICOR Unified Chassis
I know these stations have jumpers all over the place - backplane, cards, etc. - that all needed to be configured properly for the thing to work the way it should. I have the manuals, but I am stumped. I know I'm missing something, SOMEWHERE - my problem is: WHAT and WHERE? 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. 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
RE: [Repeater-Builder] UHF MICOR Unified Chassis
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?

RE: [Repeater-Builder] UHF MICOR Unified Chassis
I was aware that there might be previous modifications. I have 14 of these chassis I picked up from the same source, so I have been comparing them as I go along to watch for issues like that. The only thing I have found so far is two or three of them were modified for connection to an external controller, like a Zetron panel. But I am not using one of those chassis (or at least I don't think). I had some issues with connections to the cards - some of the cards themselves had bad connector pin receptacles, and in other instances the pins on the backplane were bent - but I think I have all this resolved. I'll double check the card edges to make sure the pin seats are tight. I have an extender card to work with, too, so I think that'll help.

I believe I have the other two manuals at home, but I'll double check the numbers when I get home this afternoon. Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com On Behalf Of Eric Lemmon Mark, If you're not going to use your repeater as a community repeater, then you don't need the community repeater supplement. There are two Motorola manuals that you do need: 6881025E50 UHF Station Instruction manual, NLA 6881025E60 Control Applications Supplement, NLA Since both of these important documents are now cancelled and NLA from Motorola Parts, they are in the queue to be scanned. Once you have the manuals in hand, you can re-configure the jumpers to restore standalone repeater operation. 73, Eric Lemmon WB6FLY

RE: [Repeater-Builder] UHF MICOR Unified Chassis
Mark, With the capability to have 16 users, I am guessing that it is more likely to be a community repeater station than a PURC station. Of course, there may be components that are common to both. Since you already have the manuals you need for a basic Micor repeater, you might consider swapping the TRN6421A backplane for a standard TLN5644A backplane. That way, you can use readily-available modules, and not worry about finding new manuals. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of n9wys Sent: Sunday, July 27, 2008 4:56 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] UHF MICOR Unified Chassis I looked at 7 of the 14 chassis I have; the ones I looked at were *all* TRN6421 - including those with what appeared to be the Zetron interface wiring.

Re: [Repeater-Builder] UHF MICOR Unified Chassis
You have what were referred to as Community Repeater stations. Before LTR trunking and 800 MHz there were community or shared repeater stations everywhere used heavily by businesses small and large. There is a seperate manual addition which deals with this station. I'll check my files tomorrow. Basically (going from memory) the discriminator signal leaves the RX and goes to the SQ gate and the Master Decoder. Based on which PL or DPL codes are activated on the Four User Modules the signal is either repeated or ignored. Usually the code that is received is transmitted, however it is possible via the Diode Logic and Multi PL or DPL encoder cards to translate the incoming code to another outgoing code.

RE: [Repeater-Builder] UHF MICOR Unified Chassis
Mark, I did a little research on the 3rd Street site, and I am convinced that you have a community repeater. The manual you need is 6881025E55, which supplements the 6881025E50 manual that you already have, for the basic station.

RE: [Repeater-Builder] UHF MICOR Unified Chassis
Joe and Eric, OK, many thanks. I bought that manual earlier today from an eBay seller for $14 -- MANUAL #68P81025E55-B. (Eric, I see the reference you sent wants $20 and it's an older manual to boot.) The seller said it will be shipped first thing tomorrow, so I guess now I just sit and wait. Hopefully when it gets here I'll have one of those Ah-HAH! moments... ;-) Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of Joe Burkleo 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 community repeater manual shows up. (I think I remember you saying you had one coming.) Then it will all become clear as mud and the pieces will start falling into place for you. I will go through my manuals tomorrow and verify what Eric and I are thinking. 73, Joe - WA7JAW From: Repeater-Builder@yahoogroups.com On Behalf Of Eric Lemmon Mark, I did a little research on the 3rd Street site, and I am convinced that you have a community repeater.
