St Cloud
St Clous is exclusively on the ARMER system and has been for some time now. If you happen to have a digital scanner you may be able to hear them from Big Lake, there is a simulcast site in Sherburne County.
If you're limited to VHF you can listen to Stearns County Sherrif's Office. They're simulcast onto VHF.
Gold Cross Ambulance & Stearns County Fire is also paged on VHF so you will be able to hear them as well depending on your preference.
