I would imagine somewhere around 190 Khz, your first adjacent might
notice and perhaps get a bit annoyed. But then again, use a poorly
capped M*-15 Harris exciter and you might be able to achieve the same
effect in stereo up and down the dial. :) It seems it got pretty much
everything out to the 7th adjacent.. Talk about eliminating the
competition!!
