I can copy Russian stns during daytime as far away as UA9 at times on 160= m which is similar to 600m also the MOSCOW stations can copy me on 600m= during late afternoon day light on CW. Nothing new about these conditions= . This is old hat to experenced MF operators.
I have also been copied on 137 khz during daylight hours in the USA ie ear= ly evening. using =A0CW.

Over the past days I monitored the G4JNT WSPR beacon 24/24.
During daytime I have a weak but consistent copy of Andy's signal,
average -24dB with ups and down of some dB.
During nighttime the signal is -10dB on average, with the usual deep
QSB (peaking -1dB, dips down to -20dB).
But the most interesting observation is that in the afternoon the
first peaks (from -24dB up to -8dB) occur as early as 15:45 UTC.
This is almost 1 hour before sunset (16:37 UTC) and almost 1.5 hours
before the D-layer (at mid point) goes into darkness.
