This is what Stefan is doing Mike. For information, WSPR takes up about 6Hz bandwidth and this is huge when compared with the extremely narrow bandwidths possible with very slow QRSS. Without being able to integrate signals over a long period of time in a very narrow bandwidth it would be impossible to see Stefan's signal at all. 73s Roger G3XBM On 26 June 2010 08:37, Mike-WE0H <[email protected]> wrote: Stefan, -- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk http://www.youtube.com/user/g3xbm G3XBM GQRP 1678 ISWL G11088 |
