Only time I do is at events on simplex ...
Out here in Southern CA, not a single one of my rigs is programed "closed tone" for any?
of the repeaters. Two cases-in-point immediately come to mind.
We have two high-level machines that "bump into" other legal machines 60+ miles away. I mean, you can sometimes hear the "other" machines break squelch on the "local" machine. If I were to "lock up" onto my local repeater's tone, I just might interfere with those other repeaters. Who knows if someone was calling in a traffic incident ... or just chit-chatting. But it is every ham's responsibility to NOT interfere with others' legal transmissions. Lock up the tone on those machines, and I would never know when I was interfering with someone else.
