"Top picks are QCOM and CELL"

OK, totally off-topic, but a possible technical glitch for QCOM. I have a dual-mode Sony phone, (CDMA and AMPS, little "Digital by Qualcomm" logo on the back...) and I've been underwhelmed by the quality of the digital transmissions.

I'm here in Qualcomm's backyard, and if they can't get it right in San Diego, where will they get it right?

Most of the time, there is a distinct "warble" to to the sound. I don't notice the "warble" when in analog mode, and, in fact, analog mode gives a much more pleasing sound overall.

The warble, I presume, is caused by time skew during packet assembly. It sounds a lot like RealAudio on a bad connection. They have to balance delay against the potential for these skew errors, and probably really need more buffering (which would result in delay, though.)

The less-advanced GSM system (which makes less efficient use of bandwidth) in wide use in Europe shouldn't have this problem.

I do like getting 5 1/2 hours of talk time and 55 hours of standby when in digital mode, though!

"Unfortunately", digital coverage of San Diego is pretty complete (Anza Borrego dessert and offshore are analog, but I've gotten digital on the beaches) so I always get lousey sound.

Quality was great in N.Y. recently, since GTE's roaming partner there doesn't offer 800mHz digital...
