Vern, would I be correct by using these three frequencies with both RAN tones (50) and a respective PL tone:
UNION CO SHERIFF
155.730 - RAN 50; PL 206.5
151.055 - RAN 50 ; PL 203.5
155.580 - RAN 50; PL 206.5
UNION CO FIRE/EMS
154.190 - RAN 50; PL 91.5
The 155.730 is ok
The 151.055 I've never heard any traffic, analog or digital, so I can't say that it's in use.
The 155.580 is licensed to Towns Co SO. Union (I guess) possibly uses it for mutual aid. If you're going to listen to this one, look at the Towns Co. listings as they use a different RAN code (25).
UC Fire/EMS 154.190 is ok (EMS Paging/FD Dispatch)
UC Fire TAC 155.085 RAN 50, PL 71.9 (FD Paging)
UC Fire Backup (Black Mtn./South County) 154.145 RAN 50, PL 107.2
UC Road Dept 155.925 RAN 50, PL 210.7
Good luck with it.
