[Electronics-talk] Accessible HD Radio

Wed Jul 7 16:57:21 UTC 2010

What I mean is.
you know how we have like 92.1 or 92.3 or 5 or 7, they all have odd numbers.
I heard that if its HD it will have numbers like 92.2 or 4 or 6, just like 
France has.
I may be wrong on how that works, but thats how I understand HD
