T-Hunt Overview Part 2 (Handi-Finder)

AB5SS will kickoff a T-Hunting event for the club on May 12. He’s found a very useful Direction Finder project kit, called the HANDI-Finder, which utilizes a simple CMOS oscillator to continuously switch your Handheld FM radio between two small wire loop antennas made from wire coat hangers.  Due to this phase-difference detection scheme, by adding a small handle and turning it,  a very sharp positional null can used to help one locate a signal’s direction.   It’s a perfect small project for T-Hunting.  The current pricing is $27.95 +$6 shipping which is a nice sweet spot for a DIY project.
