Future Meetings
Jesse Maxenchs Dies
For more years than I can remember, the first person who stood up to introduce himself at the BABES meetings was, "Jesse Maxenchs - Orban". (For awhile the company was TFT.) We haven't seen Jesse for a few years as he's been battling cancer. On January 23rd, Jessie died.

A contribution to the American Cancer Society has been made by SBE Chapter 40 in Jesse's memory,

Napa Valley College Students Help At SMPTE
I attended the SMPTE Winter Conference here and was very impressed by Gary Vann's students from Napa Valley College who helped out at the conference. Gary's current crop is pretty impressive. For a look at their resumes, go to

TI Digital Light Projector at Van Ness AMC
Did you know that at the AMC complex at 1000 Van Ness we have one of the 12 theaters in the country equipped for digital cinema? The Saturday night of the SMPTE Conference, a group of 200 attendees took over theater 2 to see a screening of "Toy Story 2" from Pixar.

This was a film that had never been a film. TS2 was produced on art systems for film release, but, in this case, those files were transferred to a Qubit recorder for display by a TI digital light projector (DLP). The result was a very bright clean image without film grain and projector frame dancing.

My impression was that those, who have a nostalgia for the "film look", will soon have take their liquor with the LP record buffs.

Minidisc OK
Last month I mentioned minidisc. If I was still in radio I think I'd give the minidisc some serious consideration. I bought a consumer unit and have been using it to record lectures. The ability to tag any location and then cue to the tag is very useful. The sound quality is on a par with DAT. The discs are only $2 to $2.50. The stereo recording time is 74 minutes and double that for mono.

DTV Reception
Last month I mentioned that Motorola was here in December to do some field tests. There is a link to their report at Doug Lung's

I've been to four cable head-ends to check out digital reception and at each, all of the Sutro stations came in just fine. The furthest site was Bonny Doon, in the Santa Cruz mountains. It's 49 miles from Sutro.

At my home in El Cerrito, I'm picking up KNTV-DT on channel 12 with a loop antenna. By my calculations, they're 60 miles away.

I just had email regarding testing of third generation receivers. Second generation looks pretty good but 3rd should handle dynamic multipath and portable applications.
