Re: [Swprograms] BBCWS American coverage

[John Figliozzi <jfiglio1@xxxxxxxxxxxx>]

Any technical problems aside, from what I understand only one (1)  
manufacturer expects to have a receiver at what could be called  
affordable consumer prices on the market by Christmas.  Inasmuch as  
there was a module announced as available as early as last winter, it  
really doesn't seem that manufacturers have been eager to "step up to  
the plate", to invoke an American colloquialism.  One could observe  
that DAB and DRM joined together to address these marketing problems  
that each seem to share.

DRM and DAB (as well as IBOC) do not (yet?) seem to be driven by  
consumer demand to any realistic extent.  In other words, consumers  
largely seem content with what we're used already. The only digital  
audio tranmission scheme that appears to be generating at least some  
buzz is the satellite radio business in NA.  And the jury is still  
out on that one too.
