Well, ca01 shows as being in Stockton. Presently most law enforcement there is P25 Conventional. You can use just about any P25 capable radio for that. But Modesto is in Stanislaus county and is on the trunked system referenced in post 2. That brings up many issues. If anyone changes to Phase II or if you're in a situation that suffers from Simulcast Distortion, then your present radio is likely lacking.
