Exceptional E-W F2 MUF

In the last few weeks the F2 MUF has exceeded 50MHz "across the pond" on a few occasions. I would expect this at times at the height of a good(ish) solar cycle. It would reach 8m far more often. Indeed my 8m 2.5W FT8 to a dipole was regularly spotted in Canada, the USA and Caribbean in autumn 2023 as well as this autumn. 

In my view this is where 8m FT8 could score. Just occasionally for a short period, the MUF will be high enough. These openings are far less likely to be spotted on CW or SSB, whereas with 8m FT8 and PSKreporter it is far more likely these brief openings will be noticed.

As the sunspots decline the N-S MUF may support 8m FT8 to South Africa more often than we might think.
