I caught an interesting transmission yesterday afternoon on 413.450, analog, no PL/DPL.
The message sounded exactly like an EAM you might here on GHFS (11175/8992). It was a male voice with a long coded message in phonetics. The only other content was "message to follow", but there was no message to follow. There was no callsign heard either.
The signal was very strong from my location in Franklin, so I'm thinking it was originating from the airport. 413.450 (but with a PL of 156.7) is listed in the DB as US Army Crew Alerts out of General Mitchell.
