[ARC5] BC sets and others.

[Rob Atkinson]

The spacing in the U.S. is 10 kc but every station is allowed up to 10
kc sidebands.  IBOC has wrecked that, but the 20 kc occupied analog
bandwidth was allowed via frequency assignments with regard to power,
pattern, and distance between tx sites.  One of the problems is that
FCC gradually jammed too many stations in, especially class D, so the
band is a mess now.
