32 assignments, sorted by frequency. Frequency is what your radio receives; input is what it transmits on for repeaters.

Authorization

What it takes to transmit on these channels.

Public safety

FCC · Class: Licensed

Nationwide non-federal public safety interoperability channels as published in the CISA National Interoperability Field Operations Guide (NIFOG) 2.02. Nationwide VHF/UHF interoperability channels are designated under 47 CFR 90.20(d)(80); authorized emission for those channels is 11K0F3E (2.5 kHz deviation narrowband analog FM). TRANSMIT REQUIRES A PART 90 LICENSE OR OPERATION UNDER A LICENSEE'S AUTHORITY. Amateur and GMRS operators hold no transmit privileges here. Treat every channel in this plan as receive-only unless the operator is covered by an appropriate Part 90 authorization. CTCSS tones are part of the national channel definition and are carried as structured `mode` data: 156.7 Hz plan-wide, with per-channel overrides where NIFOG differs. Default monitoring practice is still carrier squelch receive. VTAC33-38 mobile receive frequencies intentionally duplicate the VTAC11-14 simplex frequencies; they differ only in mobile transmit frequency and in mobile TX tone (136.5 Hz vs 156.7 Hz). For receive-only monitoring they add no new frequencies. VFIRE/VMED/VLAW/VSAR mutual aid channels are recorded at 12.5 kHz per the post-narrowbanding Part 90 requirement; some legacy systems are still encountered operating wideband.
