MHP-state-wide system
The troopers in Ravalli and Missoula counties use the analog version of the frequencies I posted. While Radio Reference identifies P25 state-wide interoperability system, I have not found it to be very active, at least not in the Ravalli or Missoula counties. In fact I do not even have it programmed in my scanner, as it is pretty dead. Other areas of the state and other readers may have a different experience with it. If so I would like to hear about it. In fact you will find some discussion of Montana interoperability system on RR, however, postings are rather dated and not directed at Missoula or surrounding communities. Again, I am open to hearing other points of view on this system.
