Eric, 

There is a list of the min required jumpers used in the MSR-2000 
repeater station included in my MSR-2000 to external repeater 
controller text found at the www.radiowrench.com/sonic web 
site. Working from a decafe based hazy memory... there should 
be 4 to 6 jumpers required on the back plane. And the remaining 
modules need some specific jumpers and mods depending on your 
choice of carrier squelch or ctcss (pl) operation, which can 
be set up as selectable.  

You're looking at placing the repeater into duplex mode, which 
"normally requires" specific modules be in place with a number 
of jumpers. 

Buy a used Motorola Micor Repeater Squelch Gate off Ebay, swap 
the end connector with an unused MSR Module and save big $ 

The big issue module combination wise is the transmit channel 
element ground/enable, which can be provided by the wire-line 
and/or squelch gate module.  If you pull the F1-PL/Guard Tone 
Modules in the wireline tone control combo.... or the DC-Transfer 
module in the wireline dc current loop combination... you need 
to install jumpers JU-5 and JU-6 on the new Squelch Gate Module. 

You can Email me direct if you have more questions... or I'm happy 
to answer them through the group if they don't drag out to long 
and torque off the neighbors. 

Removing the T/R Relay is no big deal so that's not a problem. 

Great repeater if you align and treat it right... 

cheers,
