Amateur Radio Direction Finding
Option D is the most physically active radio option. Amateur Radio Direction Finding (ARDF), commonly called “fox hunting,” combines radio skills with orienteering — you use a directional antenna and receiver to locate hidden transmitters in the field. It’s part scavenger hunt, part radio science, part cross-country running.

- Req 8d1 — What Is ARDF?: Understand what direction finding is and why it matters.
- Req 8d2 — Frequencies & Equipment: Learn the frequencies and gear used in fox hunting.

Getting Started
This option works best with help from a local amateur radio club. Many clubs run fox hunts as regular activities and can provide receivers, set up transmitters, and teach technique. Contact the ARRL or search for ARDF clubs in your area.
