Wouldn't it be cool to have 5.1 surround from your radio?

Neither AM nor FM are currently broadcast close to thier technical
fidelity
limits. Plenty of people are happy with the current mid-fi radio and
perfect audio reproduction, even if it were possible, would not bring in
more listeners.

I agree with that. What would attract people to HD Radio is seeing
their favorite stations (like mine: FM97) multiply into 3 or 4
channels..... thus giving more choices to the listener.

For every additional channel a station adds in IBOC, their main channel
bitrate MUST suffer, as bandwidth is taken away from it, so it of necessity
MUST cut back the bitrate. DAB in the UK suffers greatly from this. Back
when they first started broadcasting, reports are that the Eureka system
sounded quite good, but as more streams were added, and the bandwidth and
bitrate of all stations had to be throttled back, complaints of artifacting
and poor audio reproduction started coming in.

For God's sake the guy claims to be a digital engineer. Clearly he
should understand this elementary concept. You shouldn't have to explain
it to him.
