but............But...........BUT................... I thought The Almighty and Everlasting Digital Signal (Praise Be To Its Bits Eternally, Ignore That Pixellating Behind The Curtain ! ) was going to cure all the supposed ills of that nasty old NTSC demon
Can it be that ONCE AGAIN, we were fed a crap sandwich by the NATVB and the FCC ? PLEASE..tell me it ain't so !

A friend of mine has an all-channel antenna on a rotor and can get 20 analog stations. He purchased a converter to see what he could get in digital. He can only get four, and three of those pixilate quite badly. Almost everything has gone to UHF here. My area is in the fringe of two markets. UHF doesn't work as well in the hills. I doubt translators will be implemented -- too much money.
