System Notes

Note that Sites 001 (Thompson Peak), 002 (White Tanks), and 009 (Criminal Courts) carry ALL MCSO patrol traffic on the system simultaneously. All other sites are fill-in sites that carry only talkgroups required by users presently associated with that particular site. Use whichever of sites 001, 002, or 009 can be received best at your location, but generally, users in the West Valley should use the White Tanks site, users in the East Valley should use Thompson Peak, and users in Central/Downtown/South Phoenix should use Criminal Courts.
