Radio Orienteering

Amateur Radio Direction Finding (ARDF)

Welcome to Radio-O.  Here is how it works! We provide a radio receiver with a directional antenna, an orienteering map, a compass, and a finger stick. By pointing the antenna and listening to the signal you can determine the direction of the signal.  Using this information you navigate to the transmitter and punch in with your finger stick. Only the start and finish are marked on the map and it is important to keep track of where you are.  To qualify as finishing you must find at least one transmitter on your course and reach the finish within the time limit. To calculate results -- first; the number of assigned transmitters you found, then; your time on the course. We offer beginner through advanced courses, Regular BOK fees apply, and Pre-Registration is required.

Results Eno River ARDF Saturday March 27, 2021

We had perfect weather for our event. The hailstorm waited until Charles had collected all the transmitters, and just crossed the bridge. Needless to say he was pretty soggy by the time he got to the car. Thank you Charles for setting up a very good course. Several people had some of their best runs. […]
