500uW 10m WSPR (Thursday)

As I have had no 10m WSPR spots at all this week at 500uW, it would appear conditions have to be very good to get spots at this very low level. 

It will be interesting to repeat this test at 500uW in the Es season, as signals can sometimes be very strong by Es.  It is my expectation that I shall get 10m WSPR spots all over Europe with 500uW 10m WSPR in May and June. Quite a lot more would have been possible at 500mW (30dB stronger), but spots.

It is my view that everyone in the UK may legally use 10mW WSPR between 40.660 and 40.700 MHz in the ISM band without a licence. I am quite surprised more people have not taken advantage of this. This is NOT amateur radio. The ISM bands are internationally allocated and power restrictions are intended to reduce the chances of harmful interference. Callsigns can be made up, and if the format is OK, WSPRnet shows where you are being spotted. Each country has interface specifications (IR2030 in the UK) to agree power levels and other parameters.
