In the U.S. the FCC has approved a system called IBOC (In-Band On Channel) to add digitial audio to existing AM and FM stations. In broadcast radio, there isn't the luxury of unused channels that allow every station to have one analog and one digital transmitter. I haven't seen any terrestrial digital radio receivers in stores yet.

With the advent of Digital TV, I am surprised that there has not been more work done on the Broadcast side for normal radio. I would of thought that this would of been easier to implement and install, don't have to send satellites up, could all be done on the ground. Maybe I am wrong, and this is already here, just that I don't see too much mentioned about it. Maybe this group can help shed some light on it. Imagine the audio quality, being able to listen to the station you are on for the whole trip, not having to change to a different station when you get out of range. I do know there is some form of satellite radio in North America, but I have not heard too many good words about it :( So, is there anything being developed, or are we still having to use old analog AM & FM.
