Radio-Orienteering News and Results

For Southern California

Hidden transmitter hunting under international rules (also called radio-orienteering, fox-tailing, foxhunting and ARDF) now takes place regularly in southern California.  Some participants are training for upcoming national and international competitions, but most are just out there for fun and exercise. Here's the latest information on these informal sessions.

Results and photos from the session at Tri-City Park in Placentia on May 18 will be available here soon.

Next Event:  To be announced soon.  For e-mail notification of these events, you can join the southern California ARDF mailing list.

The idea was to have our annual Schabarum Regional Park ARDF session in April, before the weather gets too hot.  But the temperature got into the 90s anyway.  Nevertheless, a small group of intrepid radio-orienteers took on a difficult course set by Marvin Johnston KE6HTS with help from Dan Slater AG6HF.

We arrived to find our usual gathering and finish location blocked off because it was in use for a large-scale Scout camporee.  There was a nice shaded area not too far from the barracade, so we set up there and everyone found us with no problems.  Brooks Kachner W6BJK and his wife Susan soon arrived to get some practice on my three two-meter beginner-level transmitters nearby.

One of the five ARDF transmitters failed early on, so everyone ended up seeking the remaining four, with these results:

Due to the heat and the late start of the two-meter hunt, nobody went out to find my two 80-meter transmitters afterward. 

Thanks to Marvin and Dan for braving the heat to set a challenging course and to April Moell WA6OPS for being ready to tackle any heat-related medical problems.

Santa Fe Dam ARDF on 3/10/2013

Our mix-in with LAOC's relay event was a big success and the weather was perfect.  Five Boy Scouts and four adults from Troop 860 in Hermosa Beach came by to learn about ARDF and try it for themselves.  They were all successful at tracking down my four beginner transmitters nearby.

The main ARDF course, set by Marvin Johnston KE6HTS, was a good test of equipment and skills.  It takes a selective receiver to pick out those micro-foxes from all the RF coming from Mt. Wilson, which was visible to the north.

Quadcopter A mixed group of beginners and experts gathered at Lake Los Carneros in Goleta for ARDF on January 12.  There were a couple of easy transmitters for the first-timers and a full five-fox course that was good training for beginners and a sprint practice for the experts.  After that, Steve Miley had some some fun with his quadcopter.
