Don't worry...it isn't a "book". It is one of Radio World's usual
half-assed articles that pretends to be technical. Believe me, real
radio engineers don't learn from Radio World.

And I don't need any book or article to know that 2 different radio
signals on the same frequency, is not a good idea.

IBOC : A Broadcast System : Designed To Jam
the Fringe-Distant Competition

It is the IBOC Signal that effects the Broadcasting
Radio Station Itself.

It's the IBOC Signal Side-Bands that effectively JAMS
Both the Adjacent Channels for 10+ kHz at 1%
and 20+ kHz at 10%

The result is AM/MW Radio DX is 'o-u-t' with IBOC
and Local AM/MW Radio Stations have a Lock-on
the Local Broadcast Market by JAMMING all the
Fringe and Distant Adjacent Channels by using IBOC.

IBOC a System that Allows you to Jam the next
door neighboring Metro Area's Radio Competition
right out of Your Local Radio Market
