Ahhh... now we get the rest of the story. Yes, the MSR-2000 
Base can be converted for duplex repeat operation. It's much 
easier if you have the duplex back plane, which is the one 
with the PL and R1-Audio Modules laying horizontal above the 
main module slots. 

But the MSR-2000 like the Micor was optioned from the factory 
to operate one of many possible ways and that requires jumpers 
and certain sequence of modules come into play. 

If your now repeater was a base station (first), you need to 
ensure a number of logic functions reach the exciter (and 
receiver) to operate. The base station originally keyed into 
transmit using tone or DC and there are modules in card cage 
that provide channel element (crystal holder) ground in transmit 
mode, which in your case is probably lead through the PL Module 
on the way to the exciter.  In repeater operation the Squelch 
Gate Module provides the channel element ground. 

First:
You need to go onto the receiver and exciter board and jumper 
the channel elements to full time on (enabled). 

You need to find the two proper manuals to service the unit, 
one being just for the Modules in the back plane and the other 
the RF and specific Hardware Manual for the VHF Unit (or UHF 
unit if you have one on 450MHz). In the case of the Manual for 
the Modules, the Micor book will sub for some things (but not 
all). 

You need to make a choice... are you going with the back 
plane direct connection to your external device (ham or commercial 
controller) or are you going with the Squelch Gate Module 
interface method? 

I would "assume" your PL Module is half duplex (normal for a 
base station).  You'll notice it is the same PC-Board as the 
full duplex version, less the parts.  You can populate the board 
up to a full duplex version by using the chip from a normal 
Mitrek Mobile PL Deck. Although the manual says they are different 
part numbers, they are the same chip and I've made many a 
duplex PL Module from half duplex units.  

Another trick I've seen is to stack the TS-32 right onto the 
PL Module, often using a small sheet of aluminum with stand-off 
spacers.  

If you're willing to put the serious time into a proper 
conversion... (without giving up), we're able to try and 
help you sort through the process. 

If someone sold you a Micor Repeater Squelch Gate Module, you 
could simply change the end pins to the MSR type using the 
parts from a spare card and you'd have a working SQM, same 
as the original MSR type without the Ebay price hike. If you're 
patient to shop around on Ebay and ask various people here 
on the group for help... you would eventually find all the 
parts you need to rock and roll your base station into full 
repeater operation. 

But I also just read where you've got it working with a CAT 
Controller and you need/want the metering socket. That doesn't 
make much sense as you can meter both the exciter and receiver 
from metering ports on the back plane with it tilted down 
(as designed) for service. The original PL Module does not 
interfere with the exciter metering as built. 

s. 


 I did another conversion to it that required a TS-32 or TS-64 so I put it in.  
I wanred both incode and decod capabilities. It has a CAT controller mounted 
where the second receiver should be. Everything works great and has for over a 
year.
