[QuadList] OT--What do Mason, OH and Lakihegy, Hungary have in common? BIG Diamonds!

[Charles Park Seward]

AFN Europe had a 150 KW AM transmitter near Frankfurt. The story was it came from Berlin and was used during the war as a shortwave transmitter.  The backup generator was a U-boat engine!

Best,
Park

Lots of good stuff in my video. There is also a second video which describes WLW's 50 KW transmitters, there are 4 transmitters still in the building.
