I like it when people write up ETRs, it will look something like this...

"Camera 12 has green vertical lines in the picture... please fix it".

Please fix it? Well if you didn't ask us to fix it, we probably would have
just laughed at the ETR and went back to our other work.

Engineers ruin Christmas

Yes this is a classic... 1. There are approximately two billion children (persons under 18 years old) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (accordin...

It is actually used in other sites, including another one on that very same mountain! The antenna Chris is referring to is a Shively 6814-6R/3R interleaved antenna. It has 6 bays full spaced, with 3 bays full spaced interleaved between the main. It is 2 antennas mounted in one... I've seen interleav...

Hi Chris, Glad to see ya here! Reject power is the power returned from a device that combines RF fields. IN HD Radio you can combine the RF from two transmitters into one line. When you combine RF, most of it goes to the antenna, but by nature, a portion of it becomes rejected within the device that...

A time base corrector will do the job. A frame sync is nothing more than a TBC with a section to re-reference the video to lock to the house sync.
(Hence the name frame sync, it syncs the frames of video).

What is interesting to note, I have the JVC in the car, and make a point of explaining to people that this is not just a radio but an HD radio. When I flipped it to an FM station, as soon as it blends into HD, you can really tell (the fidelity just improves that much), and almost everyone notices. A...

What you said in the first line is a good response to what I said, that said pressure to sell non selling items... HD Radio is still wayy too new to really see if it will take off or not, despite what thoses on "other boards" say. Once it becomes standard in all automotibles then you'll see the tech...

I'm concerned

What bothers me this holiday season, I got my Sunday Providence Journal, with all the big fliers for Circuit City, Best Buy, etc... how much these big box stores are against broadcasters in general. And it's not the lack of HD radios in the flyers (I didn't see one), but the fact that each car stere...

Make sure there is no metal flashing, and you aren't touching any protruding roof nails.

OK so I put the hangars at half-wave spacing, I have to orient the hook oppisite one another to ensure my hangers, er, bays are correctly out of phase?

Great, My closet has a 24 bay antenna, waiting to go!

And the 0 ohms impedence, really makes it swing!
