A wide 100 watt signal is not bad to be next to, and I do not think people
running old gear should be made to clean it up if they do not want to.
But someone who is running 1000 watts of carrier and has 10Kc audio on it,
processed to fill the spectrum, is a different story.
I have never seen Don wide, and he always sounds great to me.
I just think its rude to park on 3875 at 9 pm and take from 3860 to 3890
with a 35 over s9 signal.
Its great that someone can generate that big and good of a signal, but its
rude to use it at prime time.
I do not care what you do with a 100 watt rig, it will not be strong enough
to trash that much spectrum.
