Your Own Little Piece of Satellite Dish Heaven

Local member Walter Johnson asked if we would mention his special estate in Jamul. He’s retired now and moving closer to family. He explains:

I live in central Jamul very near the Oak Grove Middle school and about 10 minutes from Miller Canyon Road that leads to Mt. San Miguel. I have very good line of sight to Mt. San Miguel.

At one time I had 14 satellite dishes which I used to test data broadcast modulation techniques to small and large dishes. Along with that I have a workshop equipped for satellite signal monitoring. I hate to see all this ripped out by a new owner that is not technical.

I would like to make the availability of this unique situation know to the engineers that work at Mt. San Miguel  and their friends in the industry. I have put together a simple web site that describes the property.

Good luck Walt.

Here Come the Converter Boxes – UPDATED

Got my TV Converter Box $40 Coupon for my 1995 Sony TV upstairs the other day. Already spent it on a dandy DigitalStream DSP7700T from Newcast Distributing in Calabasas. In mid-May they were out of product.  Similarly, I tried to buy the Channel Master box at Fry’s, but they weren’t ready to take coupons yet. For the system to be five months into the coupon program, there seems to be a lot of ramping up yet to do while our coupons approach expiration.

Options

Wikipedia has an exhaustive, if sparsely detailed, listing of Coupon-Eligible Converter Boxes. Take a good look at the specs available.

The first thing I notice in comparing models is that not many provide analog pass through. Too bad for the two remaining full-power analog English language, seven full power Spanish stations, and at least five lower power foreign language stations serving the San Diego market. The NTIA didn’t think of this in making the specifications?

My DigitalStream box bypasses analog when you turn off the power. That’s okay.

So I can at least take advantage of DTV’s better color processing and feed the component or at least Y/C (S-video) ports on my TV–right? Nope, not unless you buy the Channel Master CM-7000 or Apex (for which I could find no active distributor).

What about Smart Antenna processing for our market that has four major mountaintop transmission sites? A few boxes list that feature, but what consumer is going to know to look for it? Or look for a Smart Antenna?

So what did I get for my $41, including tax, shipping, and coupon discount? The DigitalStream DSP7700T found all the local digital stations with a broadband log-periodic pointed at Tijuana from Kearny Mesa, plus it found KCBS and KNBC off the back side! KNBC was on the edge of its capabilities, though. The menu is attractive, it includes a signal level bar readout, closed captioning, EPG titles, and stereo audio. I was most amazed by the reception under obvious multipath conditions since KGTV 25 and KFMB 7 were perfectly decoded off the side of the Blonder-Tongue UHF log.

June 1 UPDATE

I bought a second box, the Zenith DTT900, for $24 ($60 + tax – $40 coupon). No analog bypass or S-video, but it runs cooler. Hooked up to my 9dBi gain log-periodic and got all locals plus just about every LA station that didn’t have a San Diego co-channel. They faded somewhat later, but one might be able to overcome that with a gain antenna.

I also learned that Dish Network is offering a $40 box through their dealers with a net cost of sales tax only. Not bad. They want to ratchet up their customer base during all the box confusion.

Radio Shack’s website now lists four boxes including the DigitalStream I bought elsewhere.

A few calls have come in at work. Interestingly, most ask if we have a digital channel. Our web FAQ has been well buried by the station’s webmaster, so I can sort of understand.

A Little Help From Our Friends

Many thanks to the sponsors who help make our local chapter successful. To date, these vendors have each contributed cash to our treasury this year:

  • Computer Modules,
  • JVC,
  • Microwave Radio Corporation,
  • Piper Digital,
  • Western Technical Services,
  • Willy’s Electronics,
  • Broadcast Connection,
  • Dielectric Communications,
  • Grass Valley Thomson, and
  • Bext

We’ve received additional support in the form of valuable door prizes and accommodations from TV Magic, Rohde & Schwarz, WireCAD, SCMS, and Sangean Radio.

Our costs are sufficiently low enough that the chapter hopes to make a donation this year to the Ennes Scholarship Fund that helps put a deserving broadcast technology student through college.

FM Jammer Taken Down

A call from a listener Friday, February 15, led Clear Channel’s local Director of Engineering, John Rigg, to go on a treasure hunt.

He was told that when listening to KHTS 93.3 MHz in a car on interstate 805 east of the University City neighborhood in San Diego, they heard a loud fluttering noise. The noise, also taking out 93.1, could be heard jamming 93.3 as far away as Kearny Mesa.

John and RF specialist Stephen Frick grabbed their spectrum analyzer and a yagi and headed out to track down the interference. It didn’t take Steve and his directional antenna long to find a possible source of the signal off Whipple Avenue just three blocks away from the freeway. A tall mast and suspicious antenna loomed some 70 feet above a home in the neighborhood.  John knocked on the door there and was loudly told from inside that no one was home.

John called the FCC’s local office Monday. As early as Wednesday, an inspector told him that the owner of the antenna was known from previous contact, and after conducting a home visit, the jamming noise disappeared.

KGTV Gets New CE

New York native Andrew Lombard joined McGraw-Hill’s KGTV as the new Chief Engineer. He follows Ron Eden, who has been out on disability lately due to health problems.

For the past 8 years, Andrew served as Director of Engineering at WPTZ and WNNE in Burlington, VT-Plattsburgh, NY, a Hearst-Argyle Television company.

When pried for personal information, he listed his accomplishments: "Bringing two HDTV stations on line; regionalizing 2 stations and five remote locations into one control, monitoring, and programming location; being among the first to adopt compressed ASI streams over microwave; progressing stations out of tape-based to server-based video editing and transfer; and turning a small town TV station into a first-rate facility.

Andrew says he started 24 years ago in satellite electronics in the Air Force in Sunnyvale CA. After four years, he landed his first TV job back home in upstate New York at WCFE-PBS. And he’s done everything from mobile teleproduction, to cable origination, to DTH satellite ops.

He says he loves sailing, motorcycling, and country music. He has a family back in New York that will join him this spring.

Andrew also said he looks forward to joining the SBE chapter this year since he didn’t have a local chapter in the neighborhood back east.
