Yessiree! Since OC fire is all analog, any trunking scanner can do this. They are on the South Cell, and along with them, Costa Mesa fire dispatches, as well as south county paramedic/base station patient care .( this is interesting to listen to, esp if one has background in medical field). Of course, county law is digital encrypted, so don't hold breath to listen to that.... ...will get seizure first due to hypoxia before one can ever listen to...................
