My original plan was to let the transmitter PTT control the Micor
encoder board as usual, but supply a valid user signal present
logic input to abruptly stop the tone when there is no user signal
present... thus allowing the controller to keep the transmitter
keyed for IDs without PL tone.

Thanks Jeff!
Having someone to kick this around with is helping.
Very good point about the ratty user signal. I hadn't thought of that.
You are exactly right. I need to make sure the controller is set up

Yep, I was over-thinking the problem! Links are new to me. Somehow I
was forgetting I have control over keeping the link transmitter up
after I drop the PL tone, so I can eliminate squelch crashes at the
receive end of the link that way. All I need to do is ground that
trusty pin
Paul,
Here is my two cents worth.
I am not sure what you are using for your other equipment in your system, but
we use Micor repeaters and have a combination of Motorola Maxtrac, GE MVS, and
Johnson Challenger link radios. We always enable PL encode and decode with
reverse burst on the
