Murphy’s Law isn’t just some metaphysical clap trap. As scientifically minded as we hams are, there comes a time when you have to throw it all out the window, close your eyes and point. And whatever choice you go with, just know – it’s gonna be wrong. Never mind that the odds *should be* 50/50. Trust me, kiddo, they ain’t.
Such was the case one early June morning when I was standing around the Acapulco Diner parking lot with a group of hams from SWDCARC. We were trying to choose an initial direction to head for our fox hunt. Jerry Keltner, KB6OJE, pulled all kinds of wondrous looking techy-type ham gear out of his SUV and under his watchful eye, we constructed a gynormous PVC framed, wire-loop antenna. At the predetermined time, the fox began transmitting “VVV VVV DE W5WB FOX HUNT “and the hunt was afoot. Slowly we twisted that behemoth antenna around, listening closely for the signal null.
On a completely unrelated note, at the time I was also studying for the Extra exam. I remember some questions about that wonderful loop antenna of Jerry’s. Their major advantage of loop antennas is: They are great for direction finding because they give really good signal nulls. The major disadvantage is: They have a bi-directional pattern. Meaning when you receive a good strong signal the origination point could be straight ahead of you or directly behind. Which brings us right back to “choice” and Murphy’s Law.
But let me back up a minute and tell you how I got to be in that parking lot to begin with.
