Mobile T-Hunts for Beginners

Southern California has many mobile transmitter hunts every month, ranging from simple to very long and difficult. For hunts where everyone starts at the same place such as the Fullerton Radio Club hunt described below, you can show up there just before the hunt starts and it's likely that someone will offer you a ride-along.

For general information about southern California mobile hunts and the types of RDF equipment that our hunters like to use, see the article "Let's Go T-Hunting" at this site. Plans for building this equipment and mounting it on your vehicle are in my book. If you don't want to build your own equipment, follow this link to sources of ready-made gear.

Scheduled Hunts

Fullerton Radio Club (FRC) hunt. Go to the top of Skyline Drive in Fullerton, just east of Acacia Avenue, and sign in at about 7:45 PM on the third Saturday of each month. (Nowadays, you can only park on the north side of Skyline.) The transmitter goes on the air at 8 PM on 146.565 MHz simplex. To win, your mission is to find the transmitter (there's just one) with the shortest elapsed odometer mileage. The transmission will be continuous and be from within these boundaries:

  Along 10 freeway from 605 freeway to 71 freeway

  Along 71 freeway from 10 freeway to 91 freeway

  Straight line from 91/71 intersection to Jamboree/Chapman intersection in Orange

  Along Jamboree Road from Chapman/Jamboree to Jamboree/PCH intersection in Newport Beach

  Along PCH between Jamboree Road and San Gabriel River

  Along San Gabriel River between PCH and 22 freeway

  Along 605 freeway from 22 freeway to 10 freeway

The FRC hidden transmitter must be within 100 feet of access by standard passenger car. The hunt usually ends at 11 PM, unless the hider agrees to keep the T on the air for teams that haven't found it yet. A restaurant for post-hunt gorging and story-swapping may be announced at the finish.

South Orange Amateur Radio Association (SOARA) hunt. Start from anywhere in the Laguna Hills area on the first Sunday of the month at 1:00 PM. Listen and hunt for the hidden transmitter on 146.565 MHz simplex, but also listen to the SOARA repeater on 448.18(-) PL131.8 for hunt coordination information. The transmitter will be within these boundaries (subject to change):

  Along Highway 55 from the ocean to 91 freeway

  Along 91 freeway from 55 freeway to Orange/Riverside county line

  Along Orange Riverside and Orange/San Diego county lines from 91 freeway to the ocean

To help beginners, the hider may give some hints after a while.

Hunt-Anytime Opportunity

To test your equipment and get an idea of what it is like to go mobile transmitter hunting, Bob Thornburg WB6JPI has deployed "GeoHunt." It is a solar-powered two-meter transmitter that sends a short voice message every three minutes. You can try to track it down at any time without the pressures of competition. Be sure to sign in when you find it. For more information and maybe some clues, go to the GeoHunt page of the southern California Transmitter Hunters Web site.

See you on the hunt!

You never know what you'll find at the end of a mobile T-hunt. For the August 2001 Fullerton Radio Club hunt, I used this motorized mount (originally made by the late Clarke Harris WB6ADC) to sweep the quad slowly back and forth. It sprayed the signal up and down Pacific Coast Highway and across the buildings at Hoag Memorial Hospital in Newport Beach for lots of moving reflections. To see a dozen night-vision photos of another typical FRC T-hunt, click here.
