Anthony,
No, I can't ... we are 70 miles from the Cleveland NBC station that we
are watching (WKYC), so "off the air" is not an option. But the local
cable system (Time-Warner) has two NBC channels, channel 3 is the
standard analog NTSC signal, and channel 521 (which is what I'm watching
.... all of the "500" channels are HD (or at least digital)) is WKYC's HD
signal, and it is 1080i widescreen on all of NBC's "entertainment" shows
that are broadcast in HD.
I did send an E-Mail to WKYC asking for the technical signal
description, I'll see what response (if any) I get.
