[Electronics-talk] HD Radio

[Jude DaShiell]

hd radios where they work have more channels on them than standard radio. 
The problems with hd radio are first the extra channels aren't worth 
listening to because too much corporate interference has had radio formats 
effectively neutered in America since the 1960's and beyond.  A wider 
variety of programming used to be available and the extra stations are 
being filled up with nothing more creative than you can now hear on your 
normal radio.  One of the reasons for this is that existing carriers were 
given their own hd channels and so far as I know new competition hasn't 
yet gotten into that radio spectrum yet.  The signals are digital as 
opposed to analog so are narrower too.  The second problem with hd radio 
is that it does not and never will work in all sections of America.  If 
you want to find out if you live in one of these black holes, visit your 
local radioshack and see if they're selling hd radios yet.  If the answer 
is no, you live in an hd radio black hole and until you move into a 
covered area there's no reason for you to buy one of these sets yet.
