Berkeley / Oakland, CA - Mysterious Constant EMF Spikes 20 seconds apart

[Guest guest]

Any where I go in Berkeley and Oakland, including at the Lawrence Hall of

Science, all along Skyline Blvd, or practically everywhere in Berkeley or

Oakland California, I can see on my Cornet meter EMF spikes that are exactly 20

seconds apart. These are " twin " spikes of roughly equal power constantly 20

seconds apart, detectable at all times. Each of them can be as high as 30,000

µW/m2, or often around 600 µW/m2, depending on location. I don't think they

come from household smart meters. Are they from the electrical distribution

meters - those big round cylinders mounted on lamp posts? I can see those

cylinders everywhere, every 100 feet, all around Berkeley Oakland.

I am eager to hear from anyone on this mystery.
