Maybe if it's a relatively late-model TV with a comb filter, though
you're likely to get some smearing and artifacts even with that. NTSC
TVs simply aren't designed for that much luminance resolution.
On older NTSC TVs, there is a lowpass filter to remove the color carrier
from the luminance, so even 40 column displays wind up fuzzy, and 80
column are completely unreadable.
