That may be fine, however when you call it APCO25 it sounds like you are
saying that the Uniden / RS digital scanners would be able to monitor it.
That's not the case. You cannot monitor digital Provoice.

Should have read "on some of"...

Correct. They offer that as an option for system users. I live near a
county-wide ProVoice system. I can track it fine and monitor the analog
talkgroups, but cannot hear the digital ones even with a 785. Digital
ProVoice will never be able to be scanned.
