Average session on 472kHz WSPR TX

Last night there were no spots from Norway of my 10mW ERP 472kHz WSPR from the earth-electrode "antenna" in the ground. This may have been conditions or nobody active who could detect my signal. At the moment, I am still on 472kHz WSPR TX, but may QSY to another band later.

472kHz WSPR overnight

UPDATE 1304z:  There was another explanation: after 12 hours without 472kHz WSPR spots I noticed that Windose had closed the program, probably do an update. This really annoys me. Having re-opened the program, I am, again, getting 472kHz WSPR spots. Darn Windows!

UPDATE 1606z: I see my shack PC is telling me the PC needs to "restart after active hours". Does this mean it will turn off things overnight again? Maybe I should turn it off soon before the evening starts?

UPDATE 1736z: At about 1630z, I restarted the PC. It successfully installed and configured Windows updates, so hopefully it will run WSJT-X overnight without interruption. In the last hour 13 different stations spotted my 10mW ERP with best DX on 472kHz WSPR TX PA3FNY (330km).


UPDATE 2019z: So far today 16 stations have spotted my 10mW ERP with the  best DX being  DL/PA0EHG (493km).
