Radio orienteering (aka Amateur Radio Direction Finding, or ARDF) is a radio sport like no other. It gets you out of your shack chair and bounding through the woods or a park, using a handheld receiver and directional antenna to find a transmitter that’s located somewhere in the vicinity. People of all ages and skill levels can have fun with radio orienteering – and you don’t even need a ham radio license to join in. In this episode, we talk to USA ARDF Co-coordinator Charles Scharlau, NZØI, about how get involved in what he calls, “the only athletic radio sport.”
