Presumably the 2.5kms on 87 or 27kHz was using USB John, or at least in USB bandwidths? Assuming a mode like QRSS30 or QRSS60, this would imply that considerably further DX would be possible, even allowing for an inverse cube attenuation rate. I wonder if anyone has any lists of DX achieved using induction mode communications? 73s Roger G3XBM On 22 February 2010 17:51, John RABSON <[email protected]> wrote: If I recall correctly, G0AKN (now SK) tried audio frequencies as well as 73 and 136 kHz. G8DSU, who monitors this list, may have more information. An article by G0AKN on this subject appeared in the Jan-Feb.1999 issue of the AMRAD newsletter. More information may be found by searching online for G0AKN. -- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk http://www.youtube.com/user/G3XBM G3XBM GQRP 1678 ISWL G11088 |
