[R-390] IBOC

[Bob Young]

IBOC is trouble Roy, it is bad news on FM where it severely cuts the range, 
most people need an outside antenna to get across town stations and it is 
especially bad on the AM band. A station which used to be about 10 Kc wide 
now takes up 30 Kc, which means that for example WOR 710 now completely 
obliterates WLW 700 and WGN 720 here in MA. Although depending on 
propagation, some nights WLW obliterates WOR, other nights they ALL 
obliterate each other as they all run iBlock at night. It is becoming a big 
mess and it has hardly begun, less than 5% of AM stations are running it. 
The digital sidebands sound like some kind of terrible white noise and cover 
the adjacent channels with noise. If this is allowed to continue the AM BCB 
will die and be left to a few big 50 KW stations which is probably what they 
and iNiquity want anyway.

These links will provide you with some of the opposition from broadcasters, 
industry people and DX'ers alike, about the only people who like are the 
ones making money from it. It is a monoploy, ONE company owns the rights to 
it, licenses it and makes ALL the money from it.

It's not all that bad.
