Thanks. This is what I expected. But in the past, the canadian cablecos
had argued that removing the 42mhz upstream limitation was a huge
endeavour (they have to convicne CRTC to keep wholesale rates up, so
create artificial scarcity by claiming that replacing all those 42mhz
repeaters would cost a fortune, so they have to do node splits instead.

Arguing at CRTC is all about finding out what incumbent statements are
just spin and which are true.

Thanks for the links as well.é

But they can allocate a single very big channel, right ?  Or did you
mean a single traditional NTSC 6mhz channel ?
