I'm pretty sure this surface wave at ~0 degrees elevation is useful on (and below) the AM broadcast band (especially the lower portion) and 160 meters.
But what about at 3.5, 5, 7, 10, 14, 18, 21, 24, and 28 MHz? That's what I've been trying to figure out: exactly how useful is this radiation at zero degrees on the different ham bands? Based on my experiences --and what I've studied-- since 1976, I'm not sure that it is. 73, Mike www.w0btu.com On Sun, May 6, 2012 at 10:10 AM, Richard Fry <r...@adams.net> wrote: > Note in the link below that the value of the surface wave at 1 km at an > elevation of 50 meters is about 110 uV/m ... > http://i62.photobucket.com/albums/h85/rfry-100/Space_Surface_Wave_Compare.gif _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
