BERKELEY -- Somewhere in the vicinity, there is a fox, and it was up to the Holiday City Amateur Radio Club to find it. Of course, it wasn't a real fox. The members called this exercise a "fox hunt" because it entails a group of people tracking down their prey. One member of the club goes off on their own and starts broadcasting a signal. The club members gathered at the Holiday City South Clubhouse to begin their search. They held their antenna aloft, pointing in different directions until they found a signal. The antenna were fashioned with PVC pipes and tape measures hooked up to receivers. Amazingly, these makeshift devices were able to tune in on the right frequency. Whereas antennas that used to sit atop televisions needed to be aimed at the broadcast towers, these antennas need to be pointed toward the fox. Once they got a signal, they went to another location, just outside the Robert J. Miller Airpark. There, they took more readings. The process continued until they found the transmitter.
