KimmiKat said:I have heard HD radio and on the FM side it wasn't better then normal FM. The 3 stations here that offer it multicast (like on digital TV stations) and the multiple streams makes the main channel sound like Real Audio. AM was a little improvement though.
The downside is people with analogue hear a "hash" sound on carriers that program HD signals.
Absolute BS.
AM can sound like FM sounds now.
FM sounds better than the codec XM is using and far superior to the codec Sirius is using.
And it does nothing to make the audio on the main FM channel sound like Real Audio - its nothing like TV multicasting as the Main FM is analog and the HD is digital.
So your post is so full of it, you must work for a Satellite Radio Company.
AM does interfer with channels 2 up and down - but only within about 3 miles of an AM Transmitter that is 50,000 Watts. Considering there are very few of these (less than 50) and most are not near population centers, that will be minimal within a 3 mile radius.
The AM high end whine that plagued it was solved with the May 2005 encoder updates - long before any HD Radios were available.
So next time you want to slam something, try and at least post something with a minor amount of truth somewhere in it.
