Re: [IRCA] WBT's Digital Test - Is There Hope For A Digital AM Band?
This particular test only hits one aspect. It doesn't give any indication as to what would occur with co-channel digital stations or adjacent channels. When I look at the number of AM stations vs TV, and the number of small stations of AM; when I look at the number of FM stations vs the number which have implemented the IBOC hybrid; and when I look at the much smaller proportion of AM's which have gone that route, I just can't see full digital on AM.

Re Steve Ponder's post about the Radio Insight article (http://radioinsight.com/blog/headlines/84743/is-there-hope-for-a-digital-am-band/)... Has anybody listened to the audio clip of the test? The WBT signal goes to digital near the end of the clip, starting with the CBS top-of-hour bong and into the newscast. Yes, the sudden drop to near-zero noise is impressive... but the actual SOUND quality is gawd-awful, like an especially bad webstream. Sure, it's got more high end than the analog signal--but it's gargly, hashy, artifact-ridden, and nearly unlistenable. The analog, while bandwidth-limited, is MUCH more pleasant to listen to! FM-quality my foot (and various other extremities)! Randy Stewart Arts Producer KSMU 901 S.

Re: [IRCA] WBT's Digital Test - Is There Hope For A Digital AM
Randy, That's what I thought, too. Swishy, very artificial-sounding. You know what I do with a web stream that sounds like that? I ignore it and go somewhere else. And if that's what IBOC-only AM sounds like, that's exactly what I'd do. Although I've heard very few, so far I haven't heard, live or recorded, any AM IBOC that's pleasing to my ears. I don't like the audio artifacts. I like hearing more high frequencies, but if they come with artifacts, I'd rather not have the highs. -- Rick ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

Perhaps somebody should pass this information along to the folks at WBT. --Mike Sanburn From: randystew...@missouristate.edu To: irca@hard-core-dx.com Date: Thu, 22 Aug 2013 10:01:50 -0500 Subject: Re: [IRCA] WBT's Digital Test - Is There Hope For A Digital AM Re Steve Ponder's post about the Radio Insight article (http://radioinsight.com/blog/headlines/84743/is-there-hope-for-a-digital-am-band/)...

[IRCA] WBT's Digital Test - Is There Hope For A Digital AM
The descriptions I read below of AM IBOC describe exactly how WBZ IBOC sounds to me: horrible. AM radio sounded great years ago before the current NRSC audio mask was implemented.
