Has anyone heard when any of the New HD radio receivers or car HD recievers will hit the market? I heard August for Auto receivers but I haven't heard anything for HT receivers.

HD Radio is a reference to the upcoming digital radio system that local AM and FM station will begin ading to their existing signals over the coming few years. Some are testing now in some markets.

I think the big rollout is 2004.

Here's a link to the Ibiquity website:

Thanks for the reply, I do know what it is, I heard the auto hardware was rolling out this August but I haven't heard anything on home audio hardware.

The problem is HD radio programming format is no different than what you have on AM and FM now. Satellite radio's programming format blows away conventianal radio. Once you listen to XM...you'll never go back (okay maybe now and then for traffic and local sports) for music again.

HD radio has been delayed indefinitely due to technical problems with the signal quality. See the following for details:

iBiquity is trying to fix the problem.

My read is that there have been complaints from some AM broadcasters on the sound quality of the AM version of the system that Ibiquity says it is addressing. The FM version appears to be unaffected and receiver rollouts will continue since the proposed fix will be done within the stream to be sent by the stations, requiring no physical change in the receiver.

<<A timely PAC-enhancement decision would be compatible with Kenwood's receiver schedule because a PAC upgrade would require no software or hardware changes to existing receiver designs, Kenwood senior VP Bob Law said. If the codec is changed completely however, new receiver hardware will be required, postponing Kenwood's car audio shipments until next year >>

I could be wrong about this but the possibility that new receiver hardware would be required is what is stopping the NRSC from setting the HD radio standard. Maybe this is kind of like the IEEE 802.11g situation up until recently. Companies shipped 802.11g products before the IEEE actually set the official standard. Some units sold were guaranteed by the manufacturers to either be compliant with the upcoming standard or be upgradeable to it via a firmware patch.

The problem with audio receivers, both home and car, is that firmware upgrades are not as simple as when something is connected to a computer over a wireless link. I would think that manufacturers would wait it out before shipping product as per this comment by the ALpine executive:

Quote:
Alpine marketing VP Steve Witt said he needs a codec decision by August in order to ship Alpine car receivers in time for next year's aftermarket selling season, which begins in April
Anyone know anything definitive concerning this?
