Homing In, CQ Magazine, May 2021 -- "ARDF Makes a Comeback in 2021"
- "In places where traveling was permitted, there were restrictions against gatherings that kept hunters quarantined in their cars, unable to mingle at the hidden transmitter site or go to a restaurant afterward."
- "Many parks were closed last year and permits for events were unavailable in the ones that were open."
- "Vaccines are making it safer to gather and restrictions are now being loosened."
- "Large, heavily wooded sites with clear running spaces among the trees are ideal for ARDF. There should be some trails, but competitors need to be able to go cross-country as well."
- "In years when the ARDF World Championships take place in the fall, USA's national championships are normally in the spring to facilitate selection of ARDF Team USA and provide time for training. Anticipated COVID travel restrictions will prevent that sequence this year."
Fullerton Radio Club's almost-annual Antennas-In-The-Park foxhunt is a CQ Worldwide Foxhunting Weekend tradition. Jenna and Robert Canillas, WWØMAN and AD6XJ are ready to try the two-meter ARDF short course. Learn more about the renewal of hidden transmitter hunting activities in Homing In for May 2021.
CQ Magazine, February 2021 -- "Navy Scientists Learn RF Technology by Foxhunting"
- "We got to experience signal bounce off rocks and other surfaces, which is the bread and butter of what we do in electronic warfare."
- "Not only are there restrictions about where you can transmit, but also how much power you can run. The base has RF authorities who must give you permission to transmit."
- "What I hadn't figured on was the effect of a chain-link fence that was right next to the transmitter. When they were walking along it, they got strange readings."
- "These are really bright guys and gals who had paid close attention in class. From beginning to end of the foxhunting, they were competitive."
- "For the second hunt, I put the fox in a coffee creamer bottle with a tiny antenna and no ground plane. The signal was barely copyable at the starting point."
Thomas Hentges leads the search for a hidden transmitter on the beach in Point Mugu, California along with team members Diane Phung and Phillip Porter. This was the graduation exercise for a two-day RDF class at the Naval Air Warfare Center. Learn about the class and the long-time transmitter hunter who taught it in Homing In for February 2021.

Homing In, CQ Magazine, November 2020 -- "Put a Foxhunting Beam on Your Vehicle"
- "As often as not, the hider will be dozens of miles away running a couple of watts from a canyon, a river bed, or maybe even a sewer."
- "You need a RDF antenna that mounts on your vehicle. You don't want to be constantly stopping and getting out to take bearings."
- "With a little practice, you'll find it easy to take bearings on the fly, using 'eyeball integration' of the meter reading."
- "Some hunters prefer to use PVC element spreaders and AWG 10 or 12 solid wire formed into square elements (stiff wire). This design is more resistant to the dreaded 'quad-eating willow.'"
- "I knew I wouldn't put as many miles on the new van and it has air bags and wiring harnesses in almost every crevice, making hole-drilling a risky adventure. So I decided to try a low-impact installation using the new van's sunroof."
A 1x4 board with bearing holds the T-hunting antenna mast in place through the open sunroof on KØOV's new van. Read about the advantages of yagis and quads for two-meter transmitter hunting and see this easy-to-make mounting system in Homing In for November 2020.
Homing In appeared monthly in 73 Magazine from November 1988 until the magazine ceased publication with the September 2003 issue. My column then appeared in CQ VHF magazine, a quarterly publication, from 2004 through Fall 2013 and CQ-Plus Digital Magazine during 2014. Now it appears four times per year in CQ Magazine, which is available in print by subscription and in Amateur Radio Stores. You can also subscribe to CQ in digital form, viewable on PC, Mac, iPad, iPhone and Android. I welcome your input for future articles, so please continue to send me your news of mobile and on-foot transmitter hunt activities.
