High-def radio is here, but is anyone listening?

Radio fanatics can't get high definition tuners installed in their Lexus nor can they currently purchase one at a local Circuit City store.
But 19 Utah stations are broadcasting 31 high-definition radio channels with six more coming soon. And the University of Utah's KUER has been raising money to help it add a classical and alternative rock station to its news, talk and jazz channel.
It seems the stations are investing in technology the public isn't quite ready to embrace.
