Common Terms and Resources

The AUXFOG is the volunteer-focused counterpart to the NIFOG. It gives Amateur Radio, GMRS, and other auxiliary communicators a standardized set of frequencies, procedures, and references to effectively support emergency response.

What It Is

• AUXFOG stands for the Auxiliary Communications Field Operations Guide.

• It’s a companion document to the NIFOG, published by DHS CISA.

• Tailored specifically for auxiliary and volunteer communicators who support public safety — such as Amateur Radio (ham), GMRS, MARS, and other volunteer comms groups.

• Like NIFOG, it’s a pocket reference guide designed for use in the field.

Contents

The AUXFOG includes:

• Amateur Radio band plans (HF, VHF, UHF, digital modes).

• GMRS, FRS, CB, and other auxiliary services frequencies.

• Interoperability channels relevant to volunteer support of public safety.

• ICS (Incident Command System) communications references.

• Net operations guidance for auxiliary communications.

• Technical quick reference: phonetic alphabets, satellite phone dialing, repeater offsets, PL tones, etc.

Purpose

• Provides volunteer communicators with a standardized playbook for supporting incident communications.

• Ensures auxiliary operators can integrate smoothly with professional first responders during disasters.

• Promotes interoperability between volunteer radio services (Amateur, GMRS, etc.) and public safety agencies.
