What I call the local adapter method is just a local
cos/cor operated status tone generator. The adapters
were made to use non motorhead receivers into the voting
system, but you can easily locate the adapter at the
voter end and just trigger it with the link rx cor/cos.
Call the status tone a non signal present idle tone
that is removed with an active signal. It's used to
detect the link status/quality and set the SQM AGC
action for best S-N Voting.

The Motorola SQM circuit is really well done. Typical
Commercial Overkill, but that's what you want in public
radio service.

If you go Motorola, you'll never go back... oh wait, I've
heard that's something else. Sorry about that... :-)
