[Lowfer] Terribly noisy tonite

[Douglas D. Williams]

Very interesting Andy. I just now remembered to listen to your audio clip.
Yes, it was very windy that evening. You have a large wire antenna,
correct? I wonder if somehow the high winds were creating a static
electricity effect on your antenna and producing the howls?

I have read that, when listening to VLF "natural radio" with short, high
impedance, wideband e-probe active devices, one can sometimes hear when an
insect flies close to the antenna, due to the static electricity generated
by it's wings.

Whatever the explanation, I'm glad you recorded it.
