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

[...]but as soon as the sunrise comes, no signals are detected in the UK while the levels are 25 dB above the decode limit in the night.
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(?)...
