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.

Open event with pre-registration required: This is an open event. You don’t have to be a BOK member but you still need to pre-register. This will ensure everyone gets a receiver. Soon after registering, we will send you an e-mail letting you know that we have reserved a receiver for you. When we run out, we’ll post an announcement on the BOK website and any subsequent registrations will be put on a wait list in case someone cancels. If you’re not a member of an orienteering club, go ahead and choose “Other O Club Member” anyway in the registration form. Here is a link to the registration page. Groups of 5 or more separate entries may register using the group registration procedure.

There will be a class at 12:00. Following this, Patrick will take beginners as a group out on the course to hunt for the foxes.

Chapel Hill-Carrboro City Schools: Everyone from the CHCCS ARDF community is welcome. Note that this is not a school event. BOK fees apply. Free for BOK members. All others $10 ($5 for entry + $5 for stick rental). Several people going together count as one entry (just $10) and includes one map. Extra maps are $2 each. For more info, see What will it cost? Also, you must register with BOK, not on the usual registration page for CHCCS events. Students in middle school will need to go with a parent if they want to search for all five foxes.
