What it is
*the whole guide. no signal required.myNIFOG puts the National Interoperability Field Operations Guide (NIFOG) and the Auxiliary Communications Field Operations Guide (AUXFOG) in one searchable, fully offline app for emergency responders and auxiliary communicators — plus an integrated RF coverage estimator built on the U.S. public-domain NTIA Irregular Terrain Model.
Free. Everything included.
*chipping in unlocks nothing. that's the point.myNIFOG is free and always will be — everything is included, and nothing is locked behind payment. If it's useful to your team and you'd like to help fund future updates and hosting, you can chip in on Ko-fi. It's entirely optional and unlocks nothing extra.

myNIFOG is an independent application and is not affiliated with, sponsored by, or endorsed by CISA, FEMA, or the U.S. Department of Homeland Security. Coverage estimates are statistical planning aids, not a guarantee of radio coverage.
Frequencies, tones (CTCSS/DCS), NAC codes, and other channel parameters presented in this application may contain errors or may have changed since publication of the source documents. Verify all frequencies, tones, and channel parameters against authoritative sources and confirm with radio checks before operational use.
Information in this application regarding frequency licensing, authorization, and permitted usage may be incomplete, outdated, or inaccurate. Many frequencies referenced in the NIFOG and AUXFOG require an FCC license, NTIA authorization, agency approval, or specific eligibility to transmit. All channels — whether licensed, license-free, or federally managed — are subject to operational and technical constraints, which may include transmit power limits, antenna height and equipment restrictions, geographic limitations (including restrictions near the Canadian and Mexican borders), permitted emission modes, and license-class privileges. A license or authorization permits operation only within its specific terms. You are solely responsible for verifying all licensing, authorization, and technical requirements and for ensuring compliance with all applicable laws and regulations, including FCC rules and NTIA regulations governing federal spectrum, before transmitting on any frequency. The developers of this application assume no liability for unauthorized or non-compliant transmissions or for any harmful interference caused by your use of the information provided.
Good operating practice requires monitoring a channel before transmitting to confirm your transmission will not disrupt ongoing communications, and immediately ceasing operation if you learn your transmission is causing interference or other harm.
