Talking about remote broadcasting, how about this?
The VOA (Voice Of America) Built and maintained a broadcasting station in Bethany Ohio (North of Cincinnati) From the 1940's through the 1980's. It was the station that broadcast the Voice of freedom and democracy to the Natzi Germany area and all of Europe during WW2.
Later they broadcast behind the Iron Curtain, in to China, and where ever they could to spread the message of freedom and Democracy.
Now for the trivia----------There never was a microphone in the facility--due to fears that the broadcast station could be captured and used against us, in the 1940's when the Crosleys built it, it was designed so that all transmissions would run in via phone lines and patched in to the transmitter. Later Satellites were used, but with all that power(at that time the most powerful in the world)and the best antennas known at the time, but NEVER any microphones.
