then there's the engineers view too many engineers I talked to said that 
IBOC after sun down was a bad idea and that's been borne out by real world 
experience which is why you are starting to see stations turn off either the 
upper or lower side band to avoid adjacent channel interference.  IBOC on AM 
was a bad idea and on FM it's not much better because you're not allowed to 
modulate those IBOC carriers at more than 5 percent of total transmitter 
power to avoid first and second adjacent interference issues.  as well as 
avoiding cross talk issues which would result from injecting those carriers 
too close to the 38 kHz stereo pilot frequency.  Over here in the UK they 
are planning to totally phase out AM by 2015 they are not planning to do any 
type of AM DAB over here but I am betting the 2015 date is going to be 
pushed back.

Yeah, there is the corporate radio view and then there is the true =
public's view.
