As I am now able to WSPR on 10m TX with 500mW and at the same time WSPR on another band, I have again started up on 6m WSPR with 1W ERP from my vertical V2000 omnidirectional antenna. I was on MF until about 1435z.
WSPR on 6m has been tried on about 6-7 different days out of the Es season, but so far I have been spotted by no-one and I have seen no-one at all!. The real activity on 6m currently seems to be in Australia where the Es season is in full swing.
10m is much easier.
