## What is myNIFOG?

myNIFOG puts the National Interoperability Field Operations Guide (NIFOG v2.02) and the Auxiliary CommunicationsField Operations Guide
  (AUXFOG v1.1) in your pocket — merged, searchable, and fully offline.

  Field reference
  - Every nationwide interoperability channel: VHF low band, VHF, UHF, 700 and 800 MHz, with exact frequencies, tones, NACs, and programming
  remarks
  - Service frequencies: NOAA weather, aviation, maritime, SAR, HF, amateur, PRS, railroad, business
  - 87 reference pages: procedures, CTCSS/NAC charts, phonetic alphabet, wiring cards, checklists, antenna building, grounding, ICS
  organization
  - 22 ICS forms with block-by-block instructions · FBI 25 Cities directory
  - Big-read display for arm's-length reading · stars · share channels as ICS-205 text
  - Three editions: NIFOG only, AUXFOG only, or combined · night mode

  RF coverage estimator
  - Predict coverage for any channel from any transmitter site using NTIA's Irregular Terrain Model — the same physics engine used by
  professional planners — over real elevation data
  - Signal heatmap, link-margin classes, and voice-quality (DAQ) displays · tap any point for a terrain cross-section with line-of-sight and
  Fresnel analysis
  - Works completely offline: download terrain around you, by state, or nationwide before you deploy · share results as KMZ for Google Earth
  and ArcGIS

  Coverage estimates are statistical predictions under median conditions — a planning aid, not a guarantee of radio coverage. Verify with
  radio checks. 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.
