There is a channel 9 in Henderson. It's KVVU-DT, the digital version of analog channel 5 (channel 11 is the digital version of analog channel 10).
If it's something recent, it might be something associated with the upcoming NAB convention.
I'd recommend you contact channel 10's chief engineer, Marty Vodovoz, at <mvodovoz@xxxxxxxx>. Do it right away. Starting Wednesday, he'll probably be at the PBS Technology Conference at the MGM Grand.

I thought someone might give me some advice on this, before I strap a directional antenna to my car and load up our old 10 ton network analyzer.I installed an antenna on my roof to receive a better TV signal (for digital OTA) and according to a frequency analyzer I have a great signal (strength and carrier to noise). However, one channel (ch. 10, PBS, NTSC) is clearly overcome by a competing signal that is continuously transmitted, causing noise on the picture that almost overwhelms the visual. By the nature of the signal (random white speckles), I believe it is digital data that is being transmitted. Some tuners are bothered by it more than others (the Samsung TV tuner is worse than the Panasonic VCR), but all experience it. I can't determine the exact frequency (I haven't looked at it with a spectrum analyzer) but it is not effecting the sound much so I don't think it is the Ch.11 ATSC signal. There is no Ch 9 broadcast in Las Vegas that I know of. Adjusting the antenna helps, but does not alleviate the problem. But because the PBS signal is weaker than others, and because all transmissions are split between two mountain tops, I must point the antenna to split the difference to receive all channels equally.Now for my question: how does one go about finding the source and making it stop (other than circling the valley with a TV antenna and spectrum analyzer)? If I do find the source, how do I make it stop? Does anyone know what might be broadcasting in that area of spectrum?Dan Grimes
