What is HD radio, and how does it work? If anyone could let me know, that would be great. Thankyou.

Another short answer / cheap shot at Ibiquity: it doesn't.<P ID="signature">______________

As you have discovered, there is some disagreement about HD Radio.

Re: an actual answer

HD radio is the name being tagged onto IBOC, the company that developed the broadcast of digital sidebands. This allows AM stations to sound cleaner and FM stations to multicast more than one signal.
Good news, your old radio will work just fine.
People who like to find distant stations are upset because the sidebands bleed all over the place. But that's an entirely different discussion.

Not even "distant". IBOC, HD Radio, or whatever else you want to call it, causes interference to stations within their own local, FCC-protected signal coverage area. It may work okay out in Wyoming or Nevada where there aren't too many stations on the dial, but here in the congested Northeast, it's a total mess -- it's nearly impossible for a station here, AM or FM, to transmit IBOC without causing destructive interference to neighboring stations.

I don't agree. 550 KFYI in Phoenix now broadcasts in IBOC and it sounds very compressed. I would compare it to the whole station sounding like it's broadcasting over an older ISDN line. The average listener may not notice, but it's very obvious if you compare it to another 5000 kw station in town.

Foregive me, but are you listening with an iBOC receiver or an analogue radio?

I have posted the following question and Emailed it out several times but have yet to receive even a hint of an answere:
Will stations who run iBOC continue to process the hell out of their audio to boost loudness, bass, and trebble as they currently do (especially) on FM before transmitting it; will we still have loudness wars?<P ID="signature">______________
