It is now 1800z and I am still spotting the same stations as previously and the same stations are spotting me. I enjoy 472kHz WSPR but we do need more new stations.
It is not hard to get on the band and, as I have proved, large antennas and high ERP are not needed for WSPR. My approach using a simple transverter and FT817 will get you going.
UPDATE 1900z: I see Ive been spotted by G0HWW (29km). Not too far, but a new station.
