At 0:35 in this video of Anne Murray's 1983 song, "A Little Good News", there is a 3 tower array that collapsed in a storm, with self supporting towers. Was this WWVA?
Was this WWVA?
WWVA had at least 2 tower collapses. There was the fairly well-publicized one in 2010, but also at least one earlier collapse, on July 28, 1936. That said, I'm going to say this is not a shot of the earlier WWVA collapse (when WWVA had a 2-tower array located in West Liberty, WV as opposed to her current 3 tower arrangement in St. Clairsville, OH) as there appears to be steep, snow-capped mountainous terrain in the background. WWVA's transmistter and towers (in any of the various places they've been located in), weren't/aren't placed where there might be green, level grass around them, with snow-capped, more mountainous terrain in the background like that.Don't know whose they were but no way they were WWVA. Unless the videographer somehow traveled time to 2010 when the WWVA towers collapsed in the storm.
That was in 1989, again after the creation of this video in 1983.
I admit that I don't know much about St. Clairsville. My Mother In Law and Father In Law lived there when they were children, and we were there for a funeral for my Wife's Grandmother. We were going East on US 40, looking at the map, approaching Parshal Avenue, when I looked up and saw it very easily, just off to the Left. It was November, so the leaves were off the trees. As I recall, I just looked up and saw the towers. This is quite a bit closer to the towers than I-70.The WWVA transmitter and tower site in St. Clairsville, OH was constructed in 1941 and those (if I recall correctly) Blaw Knox towers stood until they toppled in 1990, well after the creation of the Anne Murray video in your original post was created in 1983. If you saw the WWVA tower site "clear as a bell" from I-70 and could tell everything about the place down to the topography, you've got better eyes than most as they're located quite a long distance from the highway, and past lots of hilly and tree-lined areas. Also, as I previously mentioned, no snow -capped mountainous terrain anywhere around them: WWVA Radio Towers in St Clairsville, OH (Google Maps)
Thanks. I thought I remembered them running ND, but I didn't know the power.I would assume that KGO ran at 12.5 kW Nondirectional.
Considering that the towers are only 90 degrees in electrical height, it is surprising that the Horizontal RMS value is 218.5 mV/m @ 1 mile @ 1 kW, just a little less than the Legacy Class I/Class A 225 mV/m @ 1 mile @ 1 kW efficiency. The towers are not Top Loaded. Normally, a single nondirectional tower would have to be almost 1/2 wavelength to achieve the legacy efficiency. The gain comes from the pattern concentrating the power into the horizontal. This happens because a pattern like KGO has nulls perpendicular to the line of the towers, which also affects the effective vertical radiation characteristic like a taller tower. In general three tower in line or slight dog leg endfire arrays have the same effect on efficiency as as a much taller tower.
