This year at the Dayton ham fest, I and several broadcasters got to tour the Wlw Cincinnatti transmitter site in Mason Ohio where several parts of the old and storied 500 killowatt transmitter still exist. My hat is off to K7AGE who did a superb job of recording, editing and producing the video of the tour. Those with sight will especially enjoy the pictures and schematics that are interwoven with the narration. However, even if you're totally blind, you'll find the narration fascinating. Enjoy and 73.
