87.7 Las Vegas?

D

DNezTech

Hello all
Mexicans got one heck of a clear channel. Covers the southwest side of town well. I haven't checked elsewhere. I thought lowband analog television was over? The ID is Spanish but it says Las Vegas and Inyo, CA.

Anyone have info?
 
KGHD-LP, a low-power TV station.

It's at the same site as the boosters for Exa FM 94.5 and whatever KYLI 96.7 is running. KGHD is 3kw/42m, that's a bit less than 10x the power of the boosters.

Not sure what the reference to Inyo is about.

Low-power TV is a different class of license (it differs from regular TV in ways other than just lower power), and they are allowed to remain in analog for about another three years.
 
Inyo County California - out by Death valley and Shoshone-repeater out there?

I notice my 2-13 channel armband radio still picks up a station on channel 5, I'm not sure what that is, it is FM rock, does anyone know.

I don't know of a repeater (nor why they'd have one *there*) but it sure sounds that way.

I'd be 99% sure what you're hearing on channel 5 is an image. I would expect a TV sound radio to pick up signals being broadcast about 21.4MHz above the frequency to which the radio is tuned. For TV-5, that would be 103.15MHz. If that's a radio with an analog "slide-rule" dial, you can probably tune pretty much anywhere from 97-103 FM within the limits of channel 5.

The same loophole in the FCC regulations that allow TV-6 low-power stations to operate as FM radio also apply to channel 5. But there's no point as VERY few radios tune that low -- so I'm quite confident the signal you're hearing is not actually being broadcast on channel 5.
 
The signal makes it to Centennial Hills (Northwest Las Vegas Valley) area too. But it booms in the southern valley area (Henderson).
 
The question now is...
How much percentage aural power are they running? 10% is the standard although nobody complains at 20%. At 5 KW that should be 500 watts of 25Khz deviation FM carrier on 87.75 MHz.

For full-power analog the rule was no more than 22%. 10% was indeed the most common figure, though 15% and 20% were reasonably common.

That rule doesn't apply to low-power stations. The limit for the aural power is the same as that for the visual. (3kw for low-band VHF) A napkin-sketch estimate of the 87.7 station in Chicago suggests it's running that 3kw and I strongly suspect KGHD is doing the same.
