500uW 10m WSPR TX (Monday)

My 10m WSPR TX beacon remains on with the PA turned off. According to my TinySA spectrum analyser the power is about 500uW.  After several days I have still to be spotted.

UPDATE 1100z:   It worked at 50mW and has worked in the past at 500uW, but I think conditions have to be exceptionally good for it to work at this power level, especially with higher RX noise floors these days. I shall probably return to QRO for me tomorrow (500mW!!).

    Hi Roger,

    Doing the same test as you with the WSPR-AXE-CW. Running with the PA off and just a halfwave end for 10M at 6M AGL.

    I have been spotted by EA8/DF4UE, OH6BG, I0UVN so far.

    I suspect your antenna Jason at 6m (mine is about 2m) has a few more dB "gain" at low angles. Well done!
