Missoula County frequency ID's

[blake23]

Hello to everyone.

After a recent trip to Big Sky country, I would like to confirm/id some frequencies that I have.

155.580(146.2) is listed on RR as Missoula County DES. I was listening to this freq and it sounded like either a Dispatch or Records channel. It sounded like the Dispatcher was identifying herself as "420" Can anybody help me identify this one.

The other freq is 155.700(146.2) same thing here listed as Missoula County DES.

I also noticed that the PL tones are the same as the ones used for Missoula City Police.

Any help would be appreciated

Richard
