  • Radio direction finder kit fox hound

    Are you curious where the police transmitter is, where a boat was calling from, where is that mysterious repeater jammer or maybe you just would like to join the latest radio craze - "foxhunting"? TheFoxhound connects to any radio, through the speaker jack and antenna connector and will allow you to easily zero in on the exact direction of an unknown transmitter, be it aircraft, two-way radio, ham or even TV. This direction finder uses a pair of telescopic whip antennas which are manually turned until the sensitive meter indicates the lowest reading. This direction finder uses the latest technology for trouble-free, solid operation. The antennas are alternately switched on and off using PIN diodes. The outputs are then passed thru a high-Q audio filter and synchronously detected for phase shift. A pair of LEDs tell you in which direction you should rotate the antennas- to the right or left. We provide the telescopic whip antennas and ask you to provide a two foot long "boom" on which to mount them. For an ideal boom we recommend, and give all details on, using a short length of 1/2" PVC pipe available for about a dollar at any hardware store. If you also purchase the matching case set, it easily and nicely mounts on the boom handle for a very professional assembly. And, as an added feature, we’ve included an automatic T-R switch! The T-R switch is ideal for handie-talkie usage, if you wish to transmit with your radio - go ahead, the Foxhound will sense your transmitter power andautomatically switch itself out of the circuit while you talk. It doesn’t get easier than this! Our well detailed and instructive step-by-step manual will carefully guide you to a kit that works first time - and you’ll know how it works, too. Be the one with the answers, win those transmitter hunts, track down the jammers, you’ll do it all with your Foxhound! Operates on internal 9 Volt battery or 12VDC, via a 2.1mm female power jack. Enclosure sold seperately. $84.95 shipping included in the USA.
