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

The annual San Diego area on-foot transmitter hunt brought over twenty persons to Guajome Regional Park in Oceanside.  It's a great place, not too hilly, with plenty of shade and close-by parking.  Hosts Joe Loughlin KE6PHB and Joe Corones N6SZO had their five two-meter ARDF transmitters placed and cycling in plenty of time for the 10:30 start.  Color aerial maps of the park were available for those who wanted to mark their bearings.

Four hunters went out onto the course solo, while others went out in groups of two or three.  It's no surprise that World Championships participant Bill Wright WB6CMD had the best time for all five transmitters, just 41 minutes.  But eight other singles/groups found all five transmitters, with five of them doing it in less than two hours.

By 2:30 PM, the hamburgers, cheeseburgers and hot dogs were coming off the grill onto the plates of the hungry hunters.  As they discussed their experiences on the course, everyone agreed it was a great day of radio foxhunting.

Hillcrest Park ARDF

It's been a two-decade tradition for fans of food and radio foxhunting to gather in north Orange County for "Antennas In The Park."  The first gathering took place in 1998 and it has continued annually (except for one year) ever since.  Originally at Tri-City Park in Placentia, it moved to Hillcrest Park in Fullerton in 2015 and is now headquartered at the Izaak Walton Cabin there.

This year's foxhunting turnout good and everyone was enthusiastic.  Two persons built two-meter antenna/attenuator sets from kits by Marvin Johnston KE6HTS.  Most participants started out by finding the three practice transmitters nearby.  Next, seven persons set out on the international-style two-meter course.  Somehow the controller logic of transmitter MOS got scrambled and it went off the air, so there were only four foxes to find.  Some of these hunters took time out in the middle of their searching to take part in the barbecue.  Here are the results:

Eighty meters is "the other foxhunting band."  There was one 80m transmitter to find.  Judging by the results, it was probably too close to give a sufficient challenge:

Thanks to Gene and Cheryl Thorpe, KB6CMO and KE6TZU, who arranged for use of the cabin.  Thanks to Albert Solomon AG6OF for bringing his grills and cooking the meat.  Thanks to Bob Houghton AD6QF for bringing all the vittles, except for the annual Foxhunting Weekend cake, which was bright by April Moell WA6OPS.  And thanks to everyone who came out and made it a great day in the park.

Report below by Joe Moell KØOV

Oso Viejo Community Park is a wonderful site for beginning on-foot transmitter hunters.  There is plenty of vegetation for concealing foxboxes.  There isn't much elevation change and there are paved walkways throughout.  Even though there was a major Easter weekend activity in the park, it didn't affect our session much (except for the limited parking).  Our gathering place was a spacious and shaded outside courtyard of the Norman P. Murray Community Center, just outside the room where the South Orange Amateur Radio Association (SOARA) holds its monthly meetings.

Fifteen persons signed in and most of them used their measuring-tape antennas and attenuators to seek my three practice transmitters near the courtyard.  Then they turned their attention to my five-fox ARDF course, with the transmitters all in the foliage near the paved walkways.  The shortest total course length, using these walkways, was 1.3 kilometers or 0.814 mile.  Here are the results:

Some of the participants didn't catch my request to start out on the five-fox course from the information table, so they weren't timed.

In addition to SOARA's south Orange County residents, we welcomed champion radio-orienteer Bill Wright WB6CMD from Winchester and the Kurylovich family from west Los Angeles.

Many thanks to the members of SOARA and especially Erik Wresch W6INE for sponsoring this session.  Erik also rode his bicycle around the loop afterward to pick up the ARDF transmitters.

Yuma Hamfest ARDF

Report below and photos above by Joe Corones N6SZO

This year's antenna clinic and transmitter hunt at the Yuma Hamfest and Convention was well attended by those building antennas and trying to locate hidden transmitters for the first time.  Twelve people signed in to participate.

Organizer Marvin Johnston KE6HTS provided antenna/attenuator kits and introduction.  Joe Loughlin KE6PHB and I provided support during the antenna kit construction and then hands-on instructions for the practice T's and then the five main T's set out as an international style hunt.

Thanks to Bill Elkerton W6ZM, Robin Elkerton KM6OUL, Dick Foran WB6ZAM, Jerry Petrizze W6VLF, Mike Rienzo KI6ACI, Greg Gibbs KI6RXX, Ron Johnson KK6I, Mike Johnson KD7SBX and Dave Somes WB6TFC, all from San Diego, for hanging out at the start point of the hunt and offering constructive advice to folks in need of assistance and, in many cases, accompanying them out on the course to find the T's.  Five people from the San Diego area were thoroughly indoctrinated on our local San Diego activities, issued a tri-fold and encouraged to come out and ride along on one of our Saturday night hunts.

The rain stopped a little later than expected, leaving a muddy field for the ARDF session at Lake Los Carneros on February 9.  Marvin Johnston KE6HTS got one transmitter put out, then it was time for the antenna build session.  He finished setting the course at about 10 AM.

Building antennas were Stu Forman AD6SF, president of Conejo Valley ARC and his son Harrison.

Thanks to Marvin for setting the course and to Julianne Walsh KI6DYX for helping the newcomers learn to find transmitters.  Also thanks to the hunters who helped pick up transmitters after the session.
