This varies through out the state. Some use trunked talkgroups and others use conventional frequencies. I used to hear rescue squads encode to St Francis in West Point on 39.82 mhz but I don't know if that is used anymore.
Mainly cellphones in NE Nebraska now. Some might use 155.340.
Omaha Metro ORION system and Lincoln SRS. South Central part of the state they use UHF Med channels, or they used to, also heard about 3 years ago of getting hospital on the SRS but I don't think that ever happened.
I don't think anyone uses 39.82 around West Point anymore, mainly cellphone use, but the Hospital still has the capability to use 39.82
