Sadly, radio geeks are completely unaware and unwilling to realize that HD is nothing but a pathetic and expensive attempt to pretend there is a chance to compete with ipods, etc. on their level.
WON'T HAPPEN.
Anyone who really thinks that the masses are going to retool with brand new receivers---or even bother to seek out the HD channels if they were available easily on the current receivers, is deluding themselves BADLY.
Any attempt to force the issue by changing from analog to digital will drive people further away from terrestrial radio.
All HD is going to do, is take more resources away from where they need to be spent: on TALENT and PROGRAMMING that enhances radio's strengths, not plays to it's numerous weaknesses.
There is and WILL NOT BE any buzz on HD radio.
Nobody cares except radio geeks. That is a FACT that is not about to change.
As usual, radio people are confused and misguided.
