Isn't this how some broadband services are distributed in the British

Willshaw reported that ham ops do not seem to have been adversely
affected. Are they using the same frequency régime?

Sure...ham radio has bands of frequencies all through the radio
spectrum starting at just above the AM broadcast band at 1.8 to
2.0 mHz, then (~) each multiple of that to way up in the gHz
area. Something like 3,000 MEGAHERTZ of bandwidth all told.
That's a BUNCH of bandwidth indeed. Especially if one remembers
that the whole regular 'AM broadcast band' is one megaHertz wide.
