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.

This year, the San Diego T-hunt group's contribution to the CQ World Wide Foxhunting Weekend (and BBQ) resulted in an attendance of 28 participants.  Five were from north of San Diego county (as far as Santa Barbara) and 23 were locals.  We were honored to have Joe Moell KØOV (co-author of the Transmitter Hunting book), Marvin Johnston KE6HTS (internationally known ARDF course-setter and antenna clinic guru) and Jerry Gastil K6DYD (long-time part-time local T-Hunter) join us as observers.

When the day started about 7:30, it was cold and misty.  Robert held down the fort while Joe and Joe headed out to plant the transmitters, using a ladder for three out of the five.  We figured if it was high enough, it could not be tampered with.  T-3 was secured on a conex box close to the boat ramp.  T-1 was secured in a palm tree close to the north end of the island.  T-5 was secured on a sign on the NW end of the island.  T-2 was by the entrance to Vacation Isle and was later discovered to have a bee hive within a few feet of the punch.  Finally, T-4 was secured on the very west end of the island in some bushes.  We encountered some brief showers, which apparently caused us to get the T-2 punch at the T-4 transmitter and T-4 punch at T-2.  Sorry about the confusion!  Here are the results:

The first hunter started at 10:15 and the last hunter finished at 2:23.  The BBQ was well under way with clearing skies.  Ideas were exchanged, plans were made, stories were told and we think everyone had a good time.  By 4:30, the weather was perfect, although we could not enjoy it due to packing things up, picking up the hidden T's and heading home.  We are looking forward to next year's hunt.

There was no May-gray to keep things cool at Fullerton Radio Club's annual Antennas In The Park session.  The temperature in Fullerton topped out at 94 degrees as members and friends gathered in Hillcrest Park for ARDF, food and radio fun.  It was pleasant inside the Izaak Walton cabin, where several newcomers built tape-measure yagis.  Just outside were three easy two-meter transmitters for training and antenna testing.

The five-fox ARDF course had an extra challenge because one of the transmitters went berserk and began randomly QRMing some of the others.  Nevertheless, three of the teams solved the problem by taking careful yagi bearings to distinguish between two simultaneous transmitters.  It was a quick sprint through the 40 acres for Bill Wright WB6CMD, who found all five in less than 43 minutes.  Here are the complete ARDF course results:

I was hoping that all newcomers would try to find my 80-meter transmitter, so I put it just 350 feet away.  However, most folks were too tired after completing the two-meter course.  (And they wanted to eat, too!)  Here are the 80-meter results, which was another sprint for most:

Parking was more difficult than usual this year because Fullerton city VIP's picked this day for ribbon-cutting of the refurbished fountain in the newly-landscaped Great Lawn portion of the park.  They arranged for additional public parking a quarter-mile away across the street, but they had many spaces within the park roped off to provide close parking for themselves.

Thanks to everyone who made it a great day, including Gene Thorpe KB6CMO for arranging for the cabin, Bob Houghton AD6QF for procuring the food, Albert Solomon AG6OF for barbecuing and April Moell WA6OPS for bringing and cutting the traditional Foxhunting Weekend cake.  Thanks to Marvin Johnston KE6HTS for providing the antenna building session and Tom Gaccione WB2LRH for helping to train new hunters.

It was a fine day for ARDF at Lake Los Carneros on April 7.  OK, so it rained, but only a sprinkling and it kept the temperature nice and cool.  A few of the participants warmed up by finding the three practice transmitters near our starting point in the parking lot.  That included newcomer Jay Hann, who came along with Bob Cooley.  Bob gave him some quick training and he was off to find those transmitters and then to take on the two-meter ARDF course.

Here are the results of the two-meter ARDF course, which was set by Marvin Johnston KE6HTS:

With clear blue skies and temperatures topping 80 degrees, the weather was great for our first ARDF session of the new year.  This on-foot transmitter hunting session was combined with a classic orienteering session of the Los Angeles Orienteering Club.  Marvin Johnston KE6HTS and Bill Wright WB6CMD got a workout beginning on Saturday, setting the two-meter ARDF course plus all of the LAOC classic-O courses.

My five two-meter practice transmitters were found by several participants, untimed, as they prepared for the main ARDF course.  Here are the main course results:

Newcomer Bill Moldt KM6LQD brought his Arrow VHF-UHF antennas to try RDF with them.  After that, he worked a few Oscar satellite passes from the park.

Thanks to everyone who came out!
