The DF (direction finding) techniques for radios are pretty much all in the receiver end of it. Not my specialty. However, once you get near the "crash" site, I would suggest a loud pieso beeper. We've searched for hours in weeds and tall grasses for small rockets that were within a few feet of us. A beeper would have reduced that time to seconds. -- - John Logajan @ Network Systems; 7600 Boone Ave; Brooklyn Park, MN 55428 - logajan@ns.network.com, john@logajan.mn.org, 612-424-4888, Fax 424-2853
