    Is that a recent pic? It looks like the antennas/towers are all still there. The satellite photos make it look like the antenna switch is still there. If I was closer, this would be awesome.

    Wow- guys- Wikipedia is a thing. I am looking things up real-time. Try it. There were 3 of you sitting there. Just sayin. (enjoyed all the pics and info and appreciate the vid)

    also 1000W to 250,000W is roughly 33dB - not as much as some may think- 3dB every time you double power (half an S unit) which is roughly 5.5 S units. What we have access to as hams is quite adequate for lots of contacts IMO!

    and so on....

    I asked an old timer who goes to Dayton every year if he ever toured the site. He had not but did mention the Delano, CA site and shared some interesting info (the ERP comment is basically accurate-amazing):

    "No but a ham group of us in one of our monthly “mobile cades” went to the VOA in Delano CA when it was operating with Sterna Curtains, huge open feed line and 1 mega watt ….. AM of course, and a megawatt transmitter took a 500,000 watt modulator, the transformer for which was outside and the size of a large bedroom … You could hear the voice audio through the humming of the huge transformer …. All segments were tubes in cabinets, one with an oscillator, the next a low power transmitter, the next a higher transmitter until they got to the big megawatt transmitter in a HUGE room of its own.

    Put this in google, press " view all “ on the pictures and have a look .. it was rather unbelievable and HUGE. - “Pictures VOA Delano CA”

    This is a sterba curtain antenna … a mega watt into an antenna that provides 18db at 80 meters and 23db gain at 40 meters and they operated around 20 meters, so even more gain, shoved down the throat of Russia and the Communist Block …. WAY north of 100,000,000 watts ERP.
