if the controller is decent, RB still works as it should on repeat
audio when in PL, which is all that matters.  I clipped the jumper
from the decoder to the sq chip because I wasn't getting the good
short Micor squelch with it in, even on a CSQ input.

Different ways of looking at the same thing =c}
I would cut the jumper even if I was putting together a stock CR, just
because of the interaction, and I've seen enough cases of the PL
decoder opening (even a Micor decoder) when there was no legit signal,
which would bring up the repeater.

Right-the way I did that is definitely NOT for everybody! Especially
if someone is putting up a stock repeater.

Hi Skipp:
I am using the CAT-200 Controller and have the logic line from the CTCSS I
have not hooked up yet. I will get my Controller Book out and do some more
reading. Thanks for the reply.

Hi Jim, 

The choice of Sub-Tone (ctcss) operation vs carrier 
squelch is most often done with the controller software 
once you have a "PL Detect" logic line routed to the 
controller.  

If you use the Squelch Gate Module to external repeater 
controller mod, the PL logic line is included with the 
conversion. 

www.radiowrench.com/sonic 

If you've already completed a different mod, you could 
ues the PL detect logic/pin on the back plane at the 
squelch gate module if the Micor PL detect/encode boards 
are in place.

good luck
