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!!

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.
