The database shows the frequency of those spots as 0.0015x MHz (i.e. audio rather than RF). So the station is receiving somewhere on HF but forgot to enter the correct band in his WSPR instance. All
Yes looks like Uman error, it happened 5 days ago around 20:00 UTC, over 10,000 Spots all reported in error. I am sure M0HGU would like to know if we / someone can contact him by e-mail. 73 Eddie G3Z
