So when you say "channel" you are referring to a particular frequency
rather than a number? Over here in the UK channels (in the sense that
you are saying "station") tend to have a standard number. Regional
variation is also substantially more limited than it seems to be in
the US. Also I am slightly confused by what you mean when you say that
Cox cable channel 20 primarily carries CNN. Is it not just CNN? Do
they put other programs of their own on around CNN or remove some of
CNN's shows?

I wonder if this is just a difference in terminology here. When I say
channel I mean something like NBC or the Sci Fi channel, which you
appear to be calling "stations". I think that when you say channel you
mean a particular frequency? (which I would just call a frequency).

That makes sense.
