Fox Hunts (Hidden Transmitter Search)


From time to time, hidden transmitter search exercises known as a "Fox Hunt" are held by the Club. The most recent hunt was held on Saturday, May 21st.  When the next event date is scheduled it will be posted here. For those interested in participating in future hunts (which will be announce here),  you can build a tape measure beam (see the info on this below).  Here is some information on other types of RDF units:

"Homing-type" DF antenna units:

Purchased Kit:  

There is an inexpensive ($45) direction finding device that can be purchased as a kit which works very well at locating the fox.  You can find information on their  "Searcher" direction finder kit on the RainbowKits web site.    

 Here is a direct LINK to the "Searcher" direction finding  device.

If you want to understand the technology behind this type of RDF unit, an excellent tutorial is available on the Utah Amateur Radio Club (UARC) web site.   Mike Mladejovsky, WA7ARK, designed the circuits presented on the UARC website.
