Our local NPR station, KUHF (which happens to be the only station in America's very sophisticated 4th largest city broadcasting classical music), had been promoting their new digital HD signal. I started a thread about HD radio on the Houston Audio Society web site and found that one of our members has researched the availability of HD tuners and the quality of the signal. His post on this topic can be seen at the link below. At least one other member, who subscribes to both satellite signals, tells us he will stick with satellite in spite of the poor signal quality because of the programming divrsity and the fact that the announcers are less inclined to talk over the music, as with our local jazz station. But he listens mostly in his 350Z and not on his $25K home system, so the signal quality doesn't matter so much anyway. That Sangen tuner looks very attractive at $200, and it just happens that my father sent me Christmas card with two $100 bills in it. I believe I'll stop by Fry's today.

Sometimes I get those kinds of artifacts on VoIP phones too. Audio over IP uses technologies that really don't work well together. IP technology uses packets that are sent over arbitrary paths. The system is designed for fault tolerance, and allows for packets to arrive at differengt times, not necessarily in the order sent. This is great for fault tolerance, but terrible for something like an audio stream that is, by nature, time sensitive. It's not a good system at all for audio quality, but since we've moved so far in the direction of IP, it can be pressed into service to carry digitized audio or video streams. It's a force fit, at best. But as long as the packets arrive in a timely fashion, the audio stream sounds good.
