Please enlighten me: Why is IBOC so Evil?

Because if wipes out adjacent 'weak' signals and the IBOC station
sounds
like crap if you are far enough away at night for sky wave to effect
the signal
at all.

For instance I live about 80 miles east of WHAS on 840KHz, and after
local
sunset they are unlistenable. Since they carry adverts for Lexington
businesses,
their business model clearly counts on revenue from Lexington. But
most
MW receivers fold after dark. Since I don't listen to MW it really
doesn't
effect me. But as an engineer I like to see effective and if possible
elegant
solutions. IBOC is neither.

Digital will have a place in the future of radio, but IBOC is the
wrong
solution for a non issue. With MW station revenues dropping, this
isn't
going to help them.
