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.

35.620229, -79.945040

Register on the BOK website.

Regional travel is unadvisable and our out-of-town participants have not indicated that they are coming, so this is no longer a “Regional” event, but a great weekend event featuring two BOK ARDF competitions. Of course, out-of-town participants are certainly welcome.

Charles has generously offered to set both a 2m and 80m course at Thornburg Farm, so we will meet at the Farm House on both Saturday and Sunday. For those who have the energy, please plan on helping with the control pickup at 2pm.

We recognize that Covid-19 is ubiquitous in NC, so please read and follow all our Covid-19 policies so we can all stay safe.

ARDF Practice Results Dec 9 2020

It was a very successful event. We set out 7 transmitters in seven different regions. Two regions were mostly in the exclusion zone. Those transmitters were on 3.51 on a 30/30 schedule. The other five were further out on 3.58 and on the classic 60/240 schedule. There was no beacon. The closest of the two […]

ARDF Practice at Gray Owl

We are having an ARDF practice on Sunday, December 6, 2020.
Location: 1725 Gray Owl Road, Asheboro, NC (35.634843, -79.881873)
Time: Everyone should arrive at 10am

We will put out transmitters at that time and hike to a remote location. Then we will find the transmitters on the way back to the finish which will be at the house. Then we will pick the transmitters up when everyone has finished.

Covid-19 is much worse than at any time since we have had events, so in response to this condition I am increasing the requirements for those attending this event and entering our property.
EVERYONE WILL WEAR A MINIMUM OF A 2 LAYER CLOTH MASK, SURGICAL MASK, N-95 MASK, OR OTHER APPROVED RESPIRATOR COVERING THEIR NOSE AND MOUTH WHENEVER THEY ARE WITHIN 3 METERS OF ANOTHER PERSON. MASKS WITH VENTS ARE NOT ACCEPTABLE.

As usual at Gray Owl, drive all the way in, turn around in the gravel oval, and park on the right side (east) of the driveway as you are heading out.
Do not drive on the grass – it is soft – you will get stuck.
