[GreenKeys] Very Slow Shift Frequency keying?

[Bruce Gentry]

A very interesting thought- is there any chance this was done with WLW 
at 500KW during WW2?  I think the last full power transmission was 
during the war for Pres. Roosevelt to address the Germans. I know he 
intervened with the FCC to keep the 500KW transmissions going after the 
"experimental" period.
