From the actual iBiquity handbook the rate is 96Kbps. There is no
"98Kbps" spec in the system. So going with the real figure, we find that
the bit rate is approximately one-fifteenth that of an ordinary CD, the
CD including forward error-correction. Amazing! "Virtual CD quality"
with seven percent of the data used by the CD. And using a ten-year-old
codec at that. You don't have to be an audio engineer to discover why
"HD Radio" sounds the way it does.

Well over here a broadcaster claims that a 64K Mono channel offers
superior sound quality thats Crystal Clear;!...

Who was it who said tell the people lies often enough and they become
the truth .. Dr Goebbels was it or someone similar?..
