[Motorola] MRS2000 Questions...

[KBØNLY]

I'm sure by now they no longer support it, and besides that they charge for 
tech support now unless your the original purchaser or a business entity, 
etc..  Been down that road before.

We got these free!

I think i might have the PL on transmit solved after some more pondering on 
the PL board, they removed a few jumpers and a few components, going to 
return the board to stock as i think they did that to disable the encoder on 
this board due to the multi pl encoder that was in there also.

Still no idea how to keep the receiver from muting however.  Is there an R1 
mute option jumper??
