Default Rain Static ?

environment and some other environments to believe p-noise exists because
they will not experience p-noise.


I saw P-static today on the spectrum scope of my
IC-756PRO. I bought a new backup battery and am
allowing it to power my transceiver to see how
long it will last. I tuned it to 1620, WTAW, in
College Station, TX. The typical AM pattern showed
up on the scope. The display has a memory mode where
past signals are remembered in blue while present
signals are displayed in green. It started raining
and after awhile, I went to check on my transceiver.
The display was back to normal as far as the green
display but the blue memory display was constant at
5 divisions completely across the 50 kHz covered by
the display. The carrier was only one division higher
than that blanket of noise caused by the rain. This
was 10 dB per division. I heard no thunder today.

This evidence should be repeatable for anyone with
a spectrum scope on their transceiver.
