Written by two "T-hunters" with years of practical experience in both competitive and enforcement RDFing, this book puts together for the first time a compendium of both tried-and-true and newly-developed methods of closing in on the target.  There are careful reviews of commercially available DF sets and complete construction plans for inexpensive, easy-to-make homebrew equipment, such as the Roanoke Doppler and the Happy Flyers RDF set.  Computer buffs will appreciate the complete listings for two RDF triangulation programs.  There are even some "secret weapons" to put you ahead of the competition.

Mobile T-hunting (also called foxhunting and bunny-hunting) can help police the ham bands, save lives, and be just plain fun. On-foot radio-orienteering (also called foxhunting and ARDF) is becoming a world-wide sport.  If you've never been out on a transmitter hunt, you've missed some real excitement. Getting started can be easy and fast.  You may have almost everything you need right now!  This book will help you with equipment choices and teach you the right techniques.
