G4NSJ – 10 metres propagation geomagnetic storms WSPR

20/4/25. Strange 10 metre propagation:

During the last week or so, propagation on the higher HF bands, particularly 10 metres, has been affected by severe geomagnetic storms, peaking at G4. This was the reason for low maximum usable frequencies which made DX contacts on the higher HF bands very difficult, if not impossible. You can see on the WSPR Map below that most stations transmitting on 10 metres were not being heard.

For two consecutive days, no one heard my 10m WSPR signals. I thought I had a problem with the antenna. However, on the 17th April, things began to change. My signal was heard by one station, DP0GVN, down in the Antarctic.

WSPR 10 metres dead

Broadcast Bands:

I’ve noticed that the higher frequency broadcast bands have been unusually quiet recently. The 21, 19 and 16 metre bands are usually lively during the day but, not of late. Even the 31 metre band has been dead during the last 7 days.
