And as long as the interference is not on YOUR frequency, which is sadly
all too common during contest stations heavily overdriving their rigs
with their computers and turning their microphone gains up way too
high.  I've been part of a casual multi-op for WPX this weekend, and
I've heard dozens of stations whose audio was so badly distorted that I
could not copy their call, even listening to it many times. And when
they do that, they're also usually creating lots of sideband splatter.

One of these times I'm going to make a list of the most awful ones and
post it far and wide.
