Joey is right. The population of Kittitas county does not warrant more than 1 dispatch channel for both fire and law enforcement. If you listen in Kittitas county 98% of all traffic will be on 155.655 (law) and 154.205 (fire/EMS).
I think Ellensburg PD is the 100's units on KITTCOM (155.655). I haven't checked it out and not sure if they still maintain it, but before moving over to KITTCOM for the dispatching, they use to be on 155.130. You may check that one out as a kind of C to C/Tac channel!
