Once in a while the home WSPR receiver's month of listening gets boiled down into something a little less like a dashboard and a little more like something you'd pin to a corkboard: a postcard, front and back, sent from grid square EM15 (Oklahoma City). The front is the view; flip it for the message and the fine print. Numbers come straight from the same decoder that feeds the Balloon Watch page, rolled up over a trailing window instead of live spots.
