Comments on: HD radio in office building? http://hdradioweb.com/2008/01/05/hd-radio-in-office-building/ HD Radio information portal talks about what HD Radio is, current and potential applications and features as well as options for HD Radio receivers.

HD radio signals are actually weaker than regular radio signals as Radio stations broadcast many things... In that broadcast you hear the music, they also send a signal to tell your radio to decode the stereo information, the actual stereo sepearation information, The RDS signal (telling you the call letters for instance) and the digital signal.... the digital signal is weaker by law than the main signal so if you can't catchem with a regular radio, you can't catch them at all on HD pretty much You get hardly no radio reception due to the faraday cage concept. The metal has a habit of shielding all but the strongest of signals. You never said if they are blocking by IP address or by application however (such as going to the website of a radio station 300 miles away, will it play?) Opposite..

That being the case, the HD signal would not be stronger. The assumption being is that digital radios will be looking for a stream of '0's and '1's which should be easier to find in the air. The only difference between digital and FM is that for FM the signal contains analogue information. Unfortunately with digital, you either have everything or nothing, whereas FM you can hear the signal degrade with more white noise (hissing and crackling).
