[AMRadio] RF Ammeters (Was AM Bandwidth)

[Kim Elmore]

I'd think that it should by indicating a current increase greater (or 
less for negative shift) than that expected under 100% modulation. By 
definition, an asymmetric audio source (positive peaks larger than 
negative peaks or vice versa) is not stationary and so results in an 
average DC offset. This would produce carrier shift, wouldn't it?
