Well, actually Fire is part of CONFIRE which is mostly in the clear. OP: Use the East Valley and Mountain sites. From the dB, program all the non "DE" marked 2-FIRE groups. Some Fireground talk is still handled on direct, so you won't hear it unless you're close, like if you're near the airport or REV, and the incident is a train vs car in San T canyon. After listening awhile, you will find what talkgroups are interesting to you, and can adjust accordingly.
