10 USA reports running 50mW on 10m WSPR

I think 10m has closed for me to the USA for the day.   I'll leave 10m WSPR running a little longer just in case.  At 2010z, 10 reports had been received, all at 50mW and all from stations in the USA. This was an interesting experiment as I know my antenna is not the best. 500mW seems almost like high power now!

The FT817 was set at 500mW and a good quality rotary attenuator (set to 10dB insertion loss) added as close as possible to the rig, therefore producing 50mW into the antenna lead and antenna. Because the cable will have some loss at 28MHz (1dB?) the actual radiated power will have been a little under 50mW.

UPDATE 2100z:  The 10m band has definitely closed here to the USA. Only G4IKZ (local) spotting me now. at 50mW.
10m WSPR spots running 50mW today
