10m 500uW WSPR TX (Wednesday)

My 500uW (0.5mW) signal has already been spotted by EA8BFK (2880km) . 


The beacon is pre-programmed to report 500mW even though the actual output is just 0.5mW!! The QRPP power is confirmed by spectrum analyser.

UPDATE 1152z:  Now spotted 5 times today by EA8BFK. USA afternoon?

UPDATE 1519z:   No further spots of me. Not surprisingly, single hop F2 is the most successful. I guess the USA is at least 2 hops, so there is far greater path loss, so the USA would require conditions to be exceptional with 0.5mW.
