[Boatanchors] Petition to eliminate exclusive CW bands

And let's face it.  I can't imagine AMers and SSBers wanting to try 
to operate in the middle of hundreds of CW signals all over them! 
 
I think there might be a few XCVRS with automatic notch filters that 
MIGHT null out TWO interfering signals, but five or more?  NAH! 
 
Much ado about not much at all!
