Yes G.., the land/sea losses ratio is definitively much higher on 472
kHz than on 137 kHz. So all the stations close to the sea clearly have
advantages.
Maybe i will get some more data for better S/N plots. I need stations in
different distances and locations who monitor for 24 hours. That would
allow to get a nice overview.
I'm not in Heidelberg tonite and so i can do no CW tonite so i will run
the TX in OP4 for another night, maybe even much longer.

No decodes Stefan... Looking on the psk map , the path to M0LMH ,
could be sea until HULL , where as I have about 240 miles
of Land , makes a big difference GW on 500 , similarly I have 559
signals from Ireland over the sea to my west in daytime

DK7FC de SWL-M0LMH (England): Op4 536 mi -26 dB in Harrogate
or 4 dB over :)

Ehm, no, i've concentrated to much on the plot of G0KTN while
writing that. M0LMH even get's daytime decodes on the lower limit,
maybe having a somehow better RX-system+location(?)...
