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.
