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

Thanks for the posting. Good info.

The history of WLW's 500,000 watt modulator and amplifier is amazing. They
drove it with the carrier their 50,000 transmitter. I recorded a tour there
a couple years ago. 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.
