While the reception of Andy's WSPR signal at 1200 km looks like somewhat of a feat ... it really wasn't. When Andy runs 'XR' in QRSS30 his signal is 'welding goggle' (bright) copy at my location for most of the night. Other distant stations routinely copied here are 'SIW' in Illinois at 1200 miles and 'WEB' in Texas at 2300 km and these are all over land paths. Propagation does seem to favor N-S rather than E-W directions.
