[BC] AM HD power levels

[W2XJ]

Gates/Harris was smart enough to keep the 833 design for 1 KW not the 
4-400 crap others dumbly adopted.

Additionally, modulation transformers used in many high power AM 
transmitters were easier to design than 1 kW rigs because the 
operating impedance was lower. This led to excellent AM fidelity up 
to the sixties when the 250 W to 1 kW allocations opened up. After 
the "no town without a radio station" fiasco began, AM transmitters 
would usually not work above 7.5 kHz and many of those designed by 
Parker Gates needed to have their proofs fudged.
