Sunday 25th April 2021: This was a pretty quiet day on the 28 MHz band with 20 stations in 9 countries heard on FT8. The poor conditions may well have been due to some geomagnetic disturbance from the sun.
The one unusual Sporadic-E opening was to Portugal with 7 stations heard from a very small geographic area.
The other unusual signals for me are those from the UK...
Txmtr Band Mode Distance Time (UTC)
G0DLV 10m FT8 288 km 10:23:59
GI4SNA 10m FT8 334 km 20:25:29
MM0IMC 10m FT8 488 km 11:15:00
G0OYQ 10m FT8 579 km 09:03:44
MM3NRX 10m FT8 620 km 07:57:59
G0DLV 10m FT8 288 km 10:23:59
GI4SNA 10m FT8 334 km 20:25:29
MM0IMC 10m FT8 488 km 11:15:00
G0OYQ 10m FT8 579 km 09:03:44
MM3NRX 10m FT8 620 km 07:57:59
I think the first two are probably via tropo but I'm not sure about the signals that are 500kms and above.
For example, I seem to hear G0OYQ near Hull nearly every day. I suspect it may be via meteor scatter and FT8 is digging out signals that are buried in the noise. How to prove it is another matter.
