I suppose it matters what you define IBOC to really mean. In Band On
Channel, just by looking at the words, may only mean "In Band" as between
the highest and lowest frequencies of the band, 530-1710 kHz for the US AM
broadcast band, and "On Channel" by being centered on a one of the common
transmitting frequencies (a multiple of 10 kHz for AM broadcast in the
US).


IBOC in the US= In band (as in not needing to use a separate frequency band)
On Channel (as in using nominally the same channel as the simultaneous
analog transmission)

For the record, I don't buy into the definition, since it's obvious that the
digital subcarriers most definately protrude into the adjacent channel's
bandwidth(s).

You and anyone else that uses their brain.
