That's some interesting history Richard!

1Hz noise field would come from meteors striking, and ionizing the
upper atmosphere. I doubt you could judge against any local sources
of noise compared to that chatter. Given that line frequency would be
6 Octaves away, if you tuned your antenna (it would be tuned, wouldn't
it?), you would have to be next to a noisy power plant to hear it.

Well, I've read that down around 60kHz there's plenty of interference due to
noise on the power lines (I doubt harmonics, probably just plain old noise
from, e.g., switching power supplies). But in any case, I'm at the point
where I need to just build something and see how it performs.
