However you CAN reduce bandwidth. Once everybody AM gets down to
CC's 5-kHz B/W you can squeeze the adjacent channel separation a
bit and force-fit a few more stations. Of course they'd be wiped
out by IBOC a little earlier. You can also (and this IS being
done right now) "piggy back" stations on FM. Example: In a few
places subcarriers formerly used for background music services are
being leased out to be programmed with special-purpose or intense
local stuff. Of course the operative word is "lease" and selling
those extras means the "new" stations would just increase
concentration of control. And then there are all the wonderful
new HD-2 "stations". Yeah, I know, not purely stations; not new
frequencies, just more prolific use of what's there.
See, more and more like those municipal sewers every day....
