VE7DXW’s “RF Seismograph” May Be Real Seismograph

[Thomas Yarish]

Some of you may remember Alex Schwartz RF Seismograph studies.

I think he is SK.

U of Arizona apparently has his data according to this ARRL report.
Active project?

Claims 75% correlation of noise spikes with certain class of quakes.

I'm not sure how the events corollated with solar events and magnetic phenomena.

Question for me would be how can these events affect the high-resolution Doppler data at various paths and polarizations. Time of year or seasonal effects due to angle of incidence and atmospheric conditions?

Hi Tom,

A clarifying question, after reading the ARRL article…is this statement the basis of your “75% correlation”?

Schwarz said that in 72% of the earthquake studies, the RF Seismograph was able to detect an increase in noise on 80 meters, typically before and after the event.

If so, that’s not a correlation but just a percent. Bear in mind, too, that only a correlation squared has a percent (proportional reduction in error) interpretation.

I haven’t read his original paper so I do not know how his “meta-analysis” of equate studies were designed so I don’t know if the other 29% did not observe the pattern.

I’m sorry he is now a SK. Thanks for the post.

73,

Frank

Hi Frank,

Thanks.

I lost connection with Alex years ago and I didn't see his "scholarship" but his posts did generate some skepticism.

Still it was a courageous adventure into a difficult science. Something to learn from.
