"I have been researching/posting on this subject for a year, and have a
zillion links set up, and know exactly how and where to find information, to
counter little punks like you and David Edurado"

-- amazing how much time you have wasted in your old age --

"A recent Arbitron/Edison Media Research study found that more than
one-third of Americans are interested in HD Radio, but nearly half said
they
would only purchase an HD Radio if it cost $100 or less."

RW: What are your thoughts about whether or how AM should go digital at
night?

Mathews: I think there are problematic issues. The long and short of it is
a
lot of AM stations, just like FMs, have been getting reception in areas
where they aren't really technically protected. . But, at some point .
they'
re going to have to give up what they've been sort of getting for free all
this time anyway, that sort of non-protected listening area. .

[TRANLATION (in the voice of Don La Fontaine): AM IBOC DXing IS FOR REAL!]

RW: Because AM has to go digital at night. .

Mathews: It's one of those things where everybody is saying, "It can't
happen."
And I've said this from the beginning on HD, none of this is a question of
"If," it's a question of "When."

RW: Do your listeners notice when you go digital?

Mathews: They have no concept unless they have an HD Radio.
