I doubt it. Part of the drive for NTSC was to make a compatible color
system that B&W sets could recieve.

Ummmm.... Muntz TVs weren't exactly common, at least on the East Coast.
I've never seen one, don't know anyone who's had one. anyway, NTSC, at
least the origional intention of it, was to transmitt full width (4.5mhz
or so) luminance. Older B&W TVs tend to have mild interference from the
color subcarrier. This wasn't an issue years ago since nobody
transmitted color anyway. Of course, today, it is. But even into the
60's, any B&W TV worth it's salt had at least 3 IF stages and delivered

I doubt he was even aware of NTSC's development, though he did breifly
market a few color sets in the 50's / 60's. After the CBS color system
flopped, it was decided that color would HAVE to be compatible with B&W.
of course, watching ATSC's development (or lack of) in the US, today,
the Feds would just obsolete existing B&W sets for whatever color
standard they'd want. I can't believe the FCC wants to kill NTSC by
2006, thus obsoleteing a few hundred million active TV sets in the US....
Hey, while we're on the color subject, is it me, or is PAL basically a
rip-off of NTSC, with the color burst flipping at every line?
