I was reminded that the CQ WW WPX contest is coming up this weekend. I’m not much of a contester, but perhaps it would be a good opportunity to get my Softrock receiver for 40m online and to record a few hours of activity as the basis for future DSP experiments. Activity is always high for this contest, and it will provide an interesting test.

This lightning strike hit almost directly overhead, and was really bright and loud.
