This is part of a pattern, since you've never been connected to cable. I
haven't made a connection like this in the last 18 days. I suspect that you
haven't made such a connection in your life, since you've never been connected
to cable. (My family was laggardly; we didn't connect to cable until October
1966.)
Also, as anybody who has actually tried to tune in cable channels while
connected to cable would tend to know, cable channels are a superset of over
the air channels. (And, I'm wondering where one configures a tv set to tune in
channels 1-13) Cable drops in 'mid-band" and "superband" channels between ota
13 and 14, but once they run out of those channels, which most do nowadays,
they start using UHF channels.
The ota (14-83) and cable UHF frequencies are the same; it's the channel
numbering that differs. (And, cable can and often does use channels above ota
69, to the limit of their amps and distro cable.)
The last time I checked, there was zero difference between channels 2-13
vis-a-vis cable and over the air. Maybe, bert, in your extensive experience
with cable connections, you have found a difference, but I doubly doubt it.
