Well, I have only one observation on this statment.  In late 70's or early 80's 
CP was the proposed solution to ghosting.  WTTV - 4 Bloomington converted to CP 
for that exact reason.  Working in the field we documented the difference at a 
receive site.  I still have the Poloraid's somewhere but it was a significant 
improvement I can say.  Of course getting the recieve ant's for CP was not an 
option, which would have given an additional improvement, per the Ch4 chief 
engineer.  That was for a single data point I grant you, and maybe as many seen 
a downgraded picture, but I can't say for sure on that.  Sure seems curious to 
me.
