New seasonal DX record on 474.2kHz last night

Last night I received several spots from DL4RAJ at 990km,which is a record, so far this year, for my QRP WSPR signals on 474.2kHz. I am hopeful of better results yet.

My 10mW EIRP maybe be a bit over-estimated as I forgot to divide the measured voltage by 1.414 to convert to RMS from peak. This means my ERP was closer to 5mW, even lower than I had expected, even though I am still showing 10mW ERP on WSPRnet.. This proves, even more, that high power and fancy big antennas are NOT needed to have fun on 474.2kHz MF.

12 unique WSPR spots in last 24 hrs with QRPP on 474.2kHz
