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 5, 2018 at Hillcrest Park in Fullerton.  (Click for directions and times.)  For e-mail notification of these events, you can join the southern California ARDF mailing list.

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!
