Radio BlanDX is a spoof! A big spoof on the DX radio listening community. But a finely done, expertly written spoof, that made it to the airwaves in the late 80's and early 90's. They sent out the strangest QSL cards, and a bulletin, that defied logic but was a direct spoof of NASWA's "FrenDX". Those lucky enough to hear one of these broadcasts and get a QSL/Bulletin, had something fun and unusual to add to their QSL collection.
BlanDX even to this day has a website. Visit it to see the depth of the joke on the DX community
