What you'll find inside
FireWave Frequencies is a quiet, no-nonsense directory built for people who already know how to use a scanner — volunteer firefighters monitoring neighboring jurisdictions, EMS dispatchers staying current on adjacent county plans, journalists covering wildfires and structure fires, ham operators tracking interop traffic during disasters, and residents who simply want to know what's happening when they hear sirens roll past.
Every state page collects the channels licensed to that state's fire and EMS mutual aid network. The nationwide NIFOG channels — VFIRE21–26, VMED28–33, VTAC11–14, VCALL10, the UHF UTAC and UMED set, and the 700/800 MHz interop ladder — are documented once and then linked from every state, because those channels are the same continent-wide. State-specific mutual aid systems (CALCORD in California, MABAS Red in Illinois, CMED in Connecticut, NJICS in New Jersey, OSCCR in Oregon, and many more) are listed on the page of the state they apply to.
Drill down to a county and you'll see the local fire dispatch and EMS dispatch channels we have on file, the agencies that use them, and the tones, modes (analog FM, P25 Phase 1, etc.), and frequency bands you'll need to program your radio. Each agency gets its own page so you can bookmark the one closest to home.
