Bob....I wholeheartedly agree....especially with your first sentence.
I have a recently installed a MFJ Hy-Tower with 90 67 foot radials and my
experience with it is the same as yours with your version of this antenna.
The only difference is I have used only 100 watts....so far.

Scott your ignorance is showing.  My HyTower look-a-like has 80 radials of 
various lengths under it and there is nothing I can't hear nor a pileup I 
can't crack, all with legal power levels.  Verticals without radials would 
match your statement however.
