    I just want to let everyone know that I’ll be releasing my fox for Field Day.  It will be transmitting on the fox hunt frequency on 2 meters (146.565 MHz) and it will be somewhere in Hollis.

    I know it’s fairly short notice but there’s still time to make a fox hunt antenna for your HT.  There are a lot of plans available on the net, just google ‘fox hunt antenna’.  For those who don’t have an HT yet, if you ask nice I might let you borrow mine or if you have an HT but no directional antenna, I have a couple of those.  My antennas have SMA connectors so you may need an adapter.

    If you haven’t experienced a fox hunt, stop by the GOTA station on Field Day and I’ll give you a brief lesson.  While you’re there, you might want to make a 20 meter contact or two.

    Sounds like fun Wayne. Can you tell us a little more about the sort of antenna we need for this? I have an arrow antenna that I could connect to an HT. Would that work? What else would I need to bring?

    Sure thing.  Arrow makes some nice antennas.  They make a loop antenna that is especially good for direction finding.  

    They also make a great 3 element 2 meter hand held antenna that would probably work fine.

    It looks a lot like the tape measure yagi I made and use.  The Arrow antennas made for satellite communications probably have more gain than you’d want for fox hunting.

    Along with the tape measure yagi I built (search google for plans) I built an eight inch loop (receive only) that attaches to my HT.  In this case, I think less gain is better. One other thing I take along is a short piece of very thin coax.  When I get close to the fox I put this on in place of an antenna and use my body to attenuate the signal and determine the direction.  A straightened paper clip might work just as well.

    There’s really nothing else to bring along for hunting.  Maybe some bug spray and watch out for poison ivy.  Hi hi.  A map of the area might be of some help.  You can draw intersecting lines to help locate the fox.

    Fox hunting is a bit of an art and takes a while to perfect.  It’s great fun for young and old, newly licensed and old timers.  Since it’s receive only you don’t even need a license.  A 2 meter receiver and various attenuated directional antennas and you’re good to go.

    If you have a half hour or so and would like to learn more about fox hunting here’s a link to a very good video.

    For those who would like to program their HT’s for the fox hunt, the fox will be howling on 146.565 MHz.  When you get close to his den, you might want to try the third harmonic (to attenuate the signal) of 439.695 MHz.

    When you find the fox, there’ll be a notebook in a plastic bag along with a pen.  Record your name, call, the date and time.

    Have fun and good luck.

    Well, Field Day is over and I’m happy to say that several people found the fox.  On Saturday, 9 brave hunters found the feisty fox.  On Sunday, 5 more folks found the little critter.  I saw a lot of happy faces as they returned from the hunt.

    It wasn’t a difficult hunt since I wanted to keep it within the confines of the high school property.  No driving around to find the fox.  Also, being our first hunt I wanted to keep it pretty easy.  From the feedback I’ve gotten, day 2 was a bit more challenging.

    In the future it won’t be so easy.  I may try to keep the little guy within the Nashua area, but you never know.  Anyone interested?

    Hi Wayne,

    Thanks for the Fox Hunt at Field Day. Guess you’ll need to try harder to “out-fox” us next time 😉
