When I first discovered WSPR I had an initial burst of great enthusiasm for it. I still think it is a great mode. It is fun to see how far signals usng low power or a very small antenna can be received.
But I have really lost most of my enthusiasm for actually using WSPR these days. Why? Because virtually all of the activity is concentrated on 30m, to the extent that there often isn't a sufficiently large number of stations monitoring any other band to guarantee the chance of a report.
I supported, indeed was involved in the inception of the idea of special activity days on other bands. These have been pretty successful in encouraging more stations to use other bands. But the rest of the time everyone goes back to 30m. Why? Personally I'm bored with getting the same old reports from the same old places on the same old band. There is nothing new to do on 30m as far as I am concerned.
