Actually...
Most AM broadcasters utilize asymmetrical modulation where they often
allow %115 positive peaks

In case you missed it, the 500 KW was in the 1930s. 250 KW of audio was not
easy to come by. Last I heard WLW was using a Harris 50 KW digital AM
transmitter. See http://download.harris.com/app/publi...d.asp?fid=1489
.. Digital here means that the AM signal is digitally synthesized at high
level. There is no modulator.

Harris has supplied MW AM transmitters of this design at carrier powers
up to 2 megawatts.

John,

I grew up in the shadow of the WLW tower and not too far away Voice of
America antenna farm.

Thanks for reminding me of this great radio history in Cincinnati.
