1400 mile FM skip

[rbrucecarter5]

Coming in on 92.5 in Houston, TX: XHRM Tijuana at 4:30 PM 1-22-16 - "Magic 92.5, the beat of San Diego" - sophisticated mix of R&B oldies, smooth jazz, and current R&B. Receiver - Pioneer Supertuner 3D in car with 31 inch whip.

Darn you folks have a good station out there! Appreciate it and support it. As we in Houston have discovered - the FM dial can be a very bleak place when programmers just don't care about listeners.

At VHF frequencies, it isn't called "skio", or even skip. It's known as atmospheric ducting.

And you're right Bruce, no radio programmer cares about their listeners. Radio station programmers are only there to play to themselves. Please.. With that logic, you must follow the Sarah Palin thought process model, because both of you say some equally bizarre stuff.

Magic 92.5 isn't that great. Listeners have to sit through "government of the republic" commercial spots in English. Which do not apply to anyone listening north of the border!

At VHF frequencies, it isn't called...skip.
It's known as atmospheric ducting.

Atmospheric ducting is a phenomenon of the lower atmosphere.
It goes out to a maximum of maybe just over one kilo-mile at best,
usually happens during cold evenings, and is stable for several hours.

Sporadic-E (layer) skip , on the other hand, is a product of and happens when sunspots excite the upper ionosphere, and begins at a minimum distance of close to one kilo-mile.
The later is subject to two types of fading: common signal fading, and the much less common selective fading or phase distortion, in which part of the signal is lost and the station sounds like a SSB signal received with an envelope detector.

Thank you, CD, for alerting me to this post.
You knew I would be compelled to correct it.

BTW...I would have located (situated) this thread there.

That's how I always differentiated ducting and skip as well. When WCBS-TV New York would overpower WGBH-TV Boston at my location in suburban Boston, that was ducting. When WESH-TV Orlando did the same, that was skip.

Absolutely.
Channel two is the most "skipable", while high VHF (ch.7-13) is better for extended tropo propagation and UHF is the best for the later.

I need to try and see how they do their translations. I've recorded about 36 minutes of the PSAs on the BCA stations. They're a hoot — the bad translation and VO work does not help.
