[bcares] Report: California Earthquakes Disrupted HF Propagation on West Coast

Thanks for the article. I have never heard of this before, but I see how it is possible with shearing strata of rocks and piezo electric effects.
It is disconcerting when anything interrupts HF radio, especially during major earthquakes (and I assume aftershocks). I printed out the article in Scientific American and will read it later.

This came to me from my old ARC in Hayward, CA.
Very interesting. I have never heard of this before.
I doubt it affected line of sight radio, I think it would be hard to Raf disrupt a repeater, as long as it has ax power and the antenna isn't laying on the ground.
Perhaps for our 120 mile links need more power? Say a kw? For 40 perhaps a hillbilly beam. IE three vertical antennas space out to make a beam, pointed to where we need to get to.
73 fer now
Don’t forget this article from February. http://www.arrl.org/news/ve7dxw-s-rf-seismograph-may-be-real-seismographtoggle quoted messageShow quoted text
