PotatoHead's Journal: Any Digital Radio Geeks out there?

I have just learned about the Ibiquity IBOC scheme. On FM, I believe it to be a tolerable improvement to radio, but what of AM? Seems to me the issues are just too complex to make for a good solution compared to existing analog methods. Low bitrates, reduced analog bandwidth, hiss/noise on existing radio units... Just put a longer article on my blog [http://www.opengeek.org/] If you have something to say at all about the state of radio today, put it there. Comments?
