MF PROPAGATION
The optimum time on MF for UK/USA is USA
sunset on 600 metres and 160 metres, this applies to East Coast
USA and spreads across North America as the night progresses until the
Optimum time for the UK to work the Pacific coast USA is UK sunrise.
This is the general picture and I have
achieved good results over the years on both 600 and 160 metres on CW
in QSO MODE
It is interesting to watch and hear through
out the night the various States appear going West as their sunset
approaches.
I also understand EI0CF has worked the East
Coast USA on 600 metres SSB
This DX excitement is not possible on
Unattended Beacon Bashing ---- A boring mode I would say!!

LF: Transatlantik WSPR on 630m
MF,
Last night there were 5 US stns copying me on 630m in WSPR. There is an
interesting difference to LF, regarding times of best SNR. The best SNR
ich achieved during the local sunset in the US, not to the time of my
local sunrise here in DL.
Bests SNRs of the 5 stations are:

There were no dramatic changes in DST and K index during the night.
However we may have to go on with the tests to confirm that observation.
