I was going through your recent posts when I came across this one on
this different NG (which i've actually been to before)..what's IBOC?

IBOC is the system by which digital audio can be transmitted over a standard

adjacent channels.

It stands for IN BAND ON CHANNEL, although really it should be called
IN BAND BETWEEN CHANNELS.
