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.

Next Event:  Saturday, May 7, 2016 on the campus of Cal Poly University in San Luis Obispo.  (Click for directions and times.)  For e-mail notification of these events, you can join the southern California ARDF mailing list.

Schabarum Regional Park is great for ARDF practice because main course competitors can start at the southeast corner of the Powder Canyon Wilderness and work their way to the finish area in a picnic grove.  Unfortunately, we discovered on arrival that Powder Canyon was closed due to rain the day before.  So the course was much shorter than planned, and start and finish were in the grove.  It was beautiful because the trees were in full bloom.  The cold front had dropped the temperature into the 40's overnight, and it only got into the 60's during our time there, making for great ARDF weather.

It was good to have two newcomers from Glendora.  With borrowed antennas and attenuators, they quickly figured out how RDF is done and found all four of my beginner two-meter transmitters nearby.  Then they went out on the main two-meter course with help and additional training from Julianne Walsh KI6DYX.

Steve Hebert K6CRW and Bob Houghton AD6QF greatly improved their individual results on the main course with help from their new MK4 "blue box" ARDF sets from Australia.  In what may be a first, all of the main course participants found all five transmitters.

Unusually warm February weather brought out a fine group of transmitter hunters to the Travel Town section of Griffith Park.  It was good to see a group from the West Side Amateur Radio Club, including Richard (KK6MRH) and Charina McDonald.  Richard is blind, but he's pretty good with a beam and a blue box.  He and another ham from the club (Rick Stutsman N6IET) tracked down the two beginner transmitters nearby, then they were ready for the main two-meter course.

The 80-meter transmitter was 1.25 km away.  You could go directly over the hills to it, or take the trail around the hills.

The cool cloudy weather was nearly perfect for on-foot transmitter hunting at Bonelli Regional Park on January 23.  Except for a very brief sprinkling in the early afternoon, the rain stayed away all day.  My practice transmitters got lots of visitors as participants checked their gear and prepared for Marvin's five-fox two-meter ARDF course.  Six tried this main hunt, with these results:

Five persons went out to find my 80-meter transmitters, which was 950 meters away.  Here are their times:
