Re: [IRCA] [ABDX] Re: [NRC-AM] WBT IBOC test

["Les Rayburn" <les@xxxxxxxxxxxxxxxx>]

Listening to the WBT IBOC Test now...just heard "Jim" from West Virginia 
call in to discuss the impact on DX'ers. Can't imagine that kind of 
emotional response is going to win over many folks within the broadcasting 
industry. The host talked about "DX'ers" afterwards...and you could nearly 
hear the distain in his voice. Keep in mind folks, it's a business...and one 
that hasn't been very competitive with FM for years now....they'll latch on 
to any technology that they think might help their ratings. "HD Radio" 
sounds catchy, but so far, it hasn't really caught on.

Truthfully, I can only barely detect some hiss on the LSB, but virtually 
nothing on USB. I could easily DX both channels on either side of WBT, but 
then again, they're not a local to me. They do boom in at S9 +20db at 
times...but even then, I can null them with a phaser, and could still DX. Of 
course, if KMOX was running IBOC...it might be a problem.

That being said, I see no real benefit to IBOC for nighttime operation...and 
certainly nothing that will warrant the interference that it will cause.
