[Amps] IMD

"AT highways speeds 55-70MPH you are  probably using
less than a third of the total HP.  I guess it is kinda the  same thing 
HUH?"

I disagree.  There is a local ham who, during calls to dx stations, runs his 
amp into a region above where he should.  It is those peaks that cause 
terrible buckshot.  If the amplifier is tested at 600 watts, and the 
distortion level is rated at that level, then that is all it should be rated 
at - period.    Any power output above guaranteed linearity is worthless.
