I'm assuming (from the fact you call it "AM BCB" and not "MW") that you're
in North America.

In which case the majority of AM BCB stations in the USA are NOT going
digital within four years. I don't think even Ibiquity, the company
pushing the digital conversion, believes it will happen anywhere near that
fast.

(many observers, myself included, believe the AM band will *never* convert
fully, or even mostly, to digital transmission)

In Canada, digital conversion within the AM band is not yet even
authorized. At the rate things are going, your problem in Canada won't be
that the majority of AM stations have gone digital - it'll be that the
majority of AM stations have moved to FM!

DS,

About half of the Canadian population lives close enough to the US
Border to easily hear US Radio Stations if they choose to; and some do
choose to.

"HD" FM Radio Works :
Then the Problem still becomes IBOC on FM and the FM Band going
Digital
"HD" FM Radio makes $ense and is a significant improvement over Analog
FM Radio. With 200 kHz Channel Spacing on the FM the IBOC {Digital}
Side Bands are not a problem.

What needs to be done in the USA is to take one or two of the old VHF
TV Channels and convert it to a new "HD" FM Radio Band where all the
new
Radio Stations are Digital and the first call for these new "HD" FM
Radio Stations goes to AM/MW Radio Stations who wish to convert over
to the new "HD" FM Radio Band. This will Open Up the AM/MW Band for
IBOC to be effective.

"HD" AM/MW Radio Does Not Work {Presently} :
While the AM/MW BCB does not currently show any significant
improvement IMHO where IBOC is concerned to date. For AM/MW IBOC to
work 1/3 to 1/2 of the current AM/MW Radio Stations would have to move
to the FM Band -and-
the AM/MW Band Spacing would have to go to 20 kHz Channel Spacing -to-
mitigate the IBOC {Digital} Side Bands from the Adjacent Channels.

and that's the way i hear it on my 'hd' radio ~ RHF
