Channels

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

What it takes to transmit on these channels.

Federal Interop Ntia

NTIA · Class: Federal assignment

Nationwide federal interoperability channels (Incident Response "IR", National Calling "NC", and Federal Law Enforcement "LE") coordinated by NTIA and published in the CISA National Interoperability Field Operations Guide (NIFOG) 2.02. TRANSMIT IS LIMITED TO FEDERAL AGENCIES AND THOSE OPERATING UNDER A FEDERAL AGENCY'S AUTHORIZATION. There is no license class available to amateur or GMRS operators that confers transmit privileges here. Treat every channel in this plan as receive-only. NC/IR repeater channels require a 167.9 Hz mobile transmit CTCSS tone and are carrier squelch on receive; that is carried as structured `mode` data (`ctcss_rx_hz` from the repeater's perspective). Simplex channels and the LE repeaters are carrier squelch. SCOPE: this plan records only the ANALOG FM federal interoperability channels. The federal law enforcement channels that are P25-only (LE 2 through LE 9 on VHF, and LE 11 through LE 15 plus LE 17 and LE 18 on UHF, all using NAC $68F) are deliberately omitted, because they are not receivable on the analog/DMR radios this dataset feeds. Add them as a separate P25 pass if a P25-capable receiver is introduced. Several IR channels intentionally share a frequency with the repeater output of a lower-numbered channel (IR 5-9 with NC 1/IR 1-4, IR 15-18 with NC 2/IR 10-12, LE 16 with LE 10). These are distinct channel designators on the same frequency, not duplicates in error.
