Future Meetings
Ray Smith at KCSM came up with a marvelous site for those of us in latitudes 37 and 38 and longitudes 121 and 122. Set your browser to

By plugging in the numbers, you'll retrieve a satellite photo of the location with a resolution of 1 meter.

They will take NAD 27 or NAD 83 numbers. I found my building but haven't had much luck with mountain tops other than Sutro.

A GPS box usually puts out NAD 83 numbers and they need to be converted to NAD 27 for use on FCC applications. (Thank you Dane Ericksen for that tip.)

[My favorite satellite photo site is produced by Microsoft known as the Teraserver - Tim Pozar]

My contribution to your site list is:

At that site you can plug in a zip code and get back a latitude and longitude for the location. At present it just handles 5 digit zip codes.

Why waste words. I got this long job announcement from Cal-State Hayward and that's what it boils down to. Knows everything; fixes everything.

The closing date was Feb 12 but I'd give it a try as living breathing geeks are hard to come by. They didn't supply a phone number or an address.

Time to Light Up
KTVU and KRON are about to answer the question: "Can you really use adjacent channels and get away with it?" They're on 56 and we're on 57 and we haven't been on together but we will be. KBHK is getting set to operate on 45 and that will be the first local DTV-NTSC combination. One other pair due this fall is KPIX ch29 (already on) and KQED ch30.

One report I've heard is that the harmonics from an IOT are a function of the way the beam forms rather than how much drive is used. I'm looking forward to Doug Lung's 2nd article on IOTs in TV Technology.

Another open question is just how much filter do you really need? KTVU, KRON, KPIX, and KGO have harmonic filters, the Dielectric waffle iron filters, and channel filters. How little can you get use and still meet the spec?

If you were certified at the Technologist, Broadcast Engineer, or Senior Broadcast Engineer level and let the expiration run past the grace period, you have until year end to apply for reinstatement of your certification. The application form requires a statement of why you think you should receive re-certification as well as other information to determine your qualifications. There is a fee of $99. Please contact me for an application form.

We sent a copy of the announcement to everyone on our chapter email list and also posted it on the Web Site.

If you have an email address, please contact Warren Reese at Warren is in charge of our email list, which we use when we need to notify members when something has happened between newsletters.

Good News - Bad News
The good news is that there is a microwave system that will permit sending NTSC and DTV over the same link. The bad news is that there are no rules to permit digital transmission on 7 or 13 gig.
