I came across this tool today:
http://www.tr4w.com/sh5/index.html
Perhaps it's well-known to SECC members, but I thought I would post the link. It can analyze your Cabrillo-formatted log to generate various statistics: QSO's by hour, by band, etc. And it will generate KML files for mapping your QSOs on Google Earth.
I haven't installed the program yet. I think it is freeware. Any comments about the quality of the program will be welcome.
