Hillcrest Park Transmitter Hunting
Saturday, May 4, 2024

Measuring-tape beamEvery spring, hams in Orange County organize an outdoor day in the park where they operate radios, find hidden transmitters and eat lots of good food.  The annual "Antennas In The Park" (AITP) event is organized by the Fullerton Radio Club.  This year, AITP will take place at Hillcrest Park in Fullerton on Saturday, May 4.

As usual, this year's AITP brings an opportunity to get involved in on-foot radio-orienteering, also called ARDF.  All ages are welcome, so bring the family.  AITP transmitter hunts are simple and informal.  They are suitable for beginners, but more advanced hunters can treat them as a "sprint."  There will be no charge for participation in the hunts, which will begin around 10:30 AM and continue until 2 PM.  Be sure to bring your two-meter handi-talkie and know how to program it to any frequency in the two-meter band.

If you don't have the antenna/attenuator system for on-foot foxhunting on two meters with your ham radio handi-talkie or scanner, a limited amount of equipment will be available for loan.  Better yet, you can easily make your own during this session.  Beginning at 10 AM, Marvin Johnston KE6HTS will conduct a clinic for building his kits for measuring-tape yagis and for 90 dB offset-type attenuators.  An assembled/tested attenuator in a special housing that goes inside the boom of the yagi is also available. (See photo at right).  If you want one or more kits, please register in advance by sending e-mail to marvin-at-west.net, so he will have the kits reserved in your name waiting for you.

It takes about an hour to put the antenna and attenuator kits together with tools and soldering irons that will be provided.  If you're not an electronic technician, don't worry because there will be plenty of experts to help you.  We want you to succeed!  Then with your HT and the kitbuilt equipment, you will be all set to hunt. 

In addition to the two-meter band, international ARDF championships also include an 80-meter band event.  At least one optional 80m transmitter is expected to be on the air for you to try.

Besides the transmitter hunts, Fullerton Radio Club members will probably have at least one HF ham radio station on the airA barbecue lunch is also being planned.  The traditional Worldwide Foxhunting Weekend cake will be served to participants in the transmitter hunts.  A few canopies and tables will be set up, but for eating and sitting around, please bring your own lawn chair.

Hillcrest Park in Fullerton is bounded on the west by Harbor Boulevard, on the north by Brea Boulevard, on the east by Lemon Street and on the south by Valley View Drive.  From the 91 Freeway, take the Harbor Boulevard exit and go north about 1.8 miles to Valley View Drive.
