When all else fails... THE KNACK

Kurt, N3JTW, alerted me to an excellent article on the blog site of the Dutch magazine Elektor. It is about a major flood in the Netherlands in 1953. Cut off from the mainland and without communication gear, OM Hossfeld whipped up the transmitter pictured above and set up a vitally important communications link. He used an 807 tube in the final. 10 Watts out on 15 meters. Note the coil wound on the bottle. The call was PA0ZRK. FB!
