A few years ago I was listening to german radio and they mentioned that during the 1920's they could broadcast world wide with only 500 watts.

I think KDKA put out 100 watts in 1920 and I think they were around 909 kc on the AM dial and on that first broadcast, they even gotten QSL's as far away as New Zealand. I'm a ham radio operator myself.
