I hear lots of amateurs describing interference and other problems on HF, but no one seems to be triangulating the offending stations. I am guessing that the real secret was in their communications with the 'spotters' to triangulate the positions. Adcock arrays http://www.airwaysmuseum.com/HF%20CR%20DF%201.htm http://members.aol.com/BmgEngInc/Adcock.html worked quite well, but they require precision in construction, as well as the site. For VHF/UHF, there are all sorts of things available N0MKJ and I used to hunt with the "fox-copter", featured in the 3/94 73 magazine. Here's some references in 73 magazine: http://www.pejla.se/ardf_litteratur.htm And a bunch of links to play with: http://www.dxzone.com/catalog/Operat...ction_Finding/ |
