My New QSL Card

While we’re on the subject of QSL cards, doesn’t it seem that nearly all of the QSL cards you get from European stations have a cathedral or castle or some similarly grand—and very old—structure?

I’m not sure why exactly, but lighthouses and amateur radio seem a good fit. There’s even an Amateur Radio Lighthouse Society. Founded in 2000 by Jim Weidner, K2JXW, the ARLHS claims to be the only society devoted exclusively to Maritime Communications and Ham Radio, Lighthouses and Lightships.

Operating Notes 7/10/07
