Amateur Radio Direction Finding (ARDF) or radio orienteering is a challenging adventure race of finding radio transmitters on foot, using radio receiver, map, and compass in diverse, wooded terrain. ARDF joins orienteering skills like the proper use of topographic maps, compass skills, and locational awareness, with technical radio direction finding skills using hand-held portable receivers and antennas. It's a great mental and physical challenge enjoyed worldwide.

ARDF is great fun for young and old alike - an opportunity for personal challenge in the great outdoors!
