That was one specific station - the infamous WLW / W8XO - the first and only US station authorized to operate at 500kW of power.[1]
To give you an idea of how powerful that is, take a look at their coverage map: http://i.imgur.com/Aigz1Zh.jpg http://i.imgur.com/Aigz1Zh.jpg
The back story is kind of interesting. It was run by Powel Crosley - a sort of 1930's version of Elon Musk. Advertising revenues from the station were so successful he applied to increase the limit from 500kW to 750kW(!).
It's a big deal in the ham community, but I only learnt latter that while US stations were limited to 50kW - other parts of the world didn't have such restrictions. Parts of the Middle East have 2,000kW stations. [2]

- gambiting 11y agoWell, the Warsaw Radio Tower used to be the tallest man-made structure in the world until it collapsed due to a guy rope failure - and it had a 2 megawatt transmitter, it could be received literally anywhere in the world: https://en.wikipedia.org/wiki/Warsaw_radio_mast https://en.wikipedia.org/wiki/Warsaw_radio_mast
- michael_h 11y agoI grew up about 5 miles from that antenna. I can't say I ever heard the radio through the wiring in my house. The Voice of America antenna array down the street though? I could hear it clearly through my stereo speakers when everything was turned off. It's been dismantled, but I can imagine the number of ghost stories that it spawned. Just sitting in your house, and then you faintly hear a man speaking German...
- bschwindHN 11y agoIt's weird seeing people on reddit who grew up in the same town as you, but it's even weirder seeing it on Hacker News for some reason. I never heard the broadcasts through metal objects in the house either, but maybe they scaled back the power in the time I grew up there. Never heard any VoA broadcasts either.
