Opening to the USA on 28 MHz as solar flux hits 140 - 22nd Dec 2021


Wednesday 22nd December 2021: I left the radio monitoring the WSPR frequency on 28 MHz for the day and I was surprised to see a lot of US stations made it across the Atlantic. If this had been on FT8 then the map would probably be ablaze with reception dots but there are a LOT fewer stations on WSPR on 10m.

It was also a day where the solar flux reached 140! I think that may be the highest value so far for cycle 25.

DP0POL: And on a final note, I also got several WSPR decodes from DP0POL, the German Antarctic research vessel which was off the west coast of Africa and making its way home.
