As I cannot access my "lab" currently (kitchen refit materials are everywhere!) I am restricted to operating from my shack, so this morning I've been trying out 28MHz WSPR with 500mW out to the halo in anticipation of my QRP WSPR transceiver design coming soon. This will be DSB, so I will need 1W RF out to get the equivalent of 500mW on the WSPR frequencies.

| 500mW 10m WSPR reports today |
Not unexpectedly, there are loads of reports on the screen when I last looked from all over Europe. The best report so far today is +8dB S/N which suggests just
500uW would have been sufficient to be spotted. I know that others have achieved similar, indeed very much better, success when the band is open. What is also intriguing are that I have been spotted within the UK at over 300km, presumably by Es or backscatter, although maybe by tropo?
I have still to finish off the 472/500kHz transverter and write this up before starting on the 10m WSPR rig, but should have the latter done quite soon. It will be fun to have a stand-alone 10m WSPR transceiver running with a little netbook.

Hello Roger
Having a new kitchen here and the materials are everywhere. Not much Radio work while the plastering and
painting going on. The floor needs to be levelled before the kitchen units are fitted and the Walls and floor tiled.
