You can no longer program in a frequency or two for your Fire Department, etc. The Oregon State Radio System that Deschutes County has moved to is a very big, complex trunked radio system with a lot of users (most of whom are not in your area). If you don't already have one you will need a P25 Phase II digital trunking scanner to receive that system, and what you want to accomplish is setting it up to receive from the Cline Butte site, and possibly the Bend site, Powell Butte and Grizzly sites as well. Those are all listed under System Frequencies on the database page. Then you want to set up which Talkgroups to scan. Just pick the ones local to your area that you're interested in. Talkgroups function essentially as channels on a trunked system.How do I know which frequency are for fire and police? There are so many numbers.
