And imagine the good folks who live in Elkton MD, trying to receive Balt NBC 
11, analog 316 KW ERP, soon to be digital 5 KW ERP.
 
My point is, your beef is with the digital power levels, NOT with 8-VSB.
 
On this list, in which more than one individual seem completely unconsolable 
about the modulation debates now approaching 10 years old, the constant 
attribution of your potential reception problems to 8-VSB just keeps this tired 
old debate alive. There are far more interesting and productive things to 
discuss, now that analog shutoff is upon us, and that newer 8-VSB receivers are 
doing quite well.
