Ok, that's interesting. This part isn't strictly related to Reception, so feel free to split to a new topic if you so wish. I'm now interested to know a bit more.
a) what happened to the old VHF bandwidth? I believe spectrum is at a premium? (Edit. I see some of it has been reallocated.)
b) How is this applied in practice? (Edit: I see from a Wikipedia article that it is a tuner function.)
So as a matter of practice, if the TV hasn't scanned for channels, it will, for instance, find virtual 5-1 on channel 41? (For my area).
As for the rest, I have a longer response that I will submit in a while.
