But HD radios cost a whole lot more than the $40-$70 DTV converter boxes. Many or most of which have an audio output. All somebody needs to do is come up with a boombox. There's something like 19 million bits per second in an ATSC transmission. They could spare the 300-500 thousand bits per second per audio channel for several "stations" and not even notice it. And that's a lot more bits (and fidelity) than what an IBOC channel can spew). They already do this in the UK with their DVB-T networks.

Double that should be plenty for a ****ty transport layer like mobile radio transmission. |
