Though I must seem to be coveting the dead-horse-beating trophy, have
you found an explanation of how the relatively low average currents that
charged precipitation imparts to an antenna cause static? My back of the
envelope calcs showed nanovolt-level signals at the receiver from this
current.


Someone reported being able to hear each individual large
snowflake. Could be that the amount of charge in a large
snowflake or a large piece of dust is magnitudes higher than
in a drop of rain, which I assume is the charge you are talking
about above. In any case, a very large number of particles
hitting around the same time could have a cumulative effect.
I personally have never heard P-static from rain but I think
I have seen it remembered on the bandscope on my IC-756PRO.

My first experience with p-static was with snow in Norway 1984. The air
was very cold and dry before it started snowing it seemed like at first
you could hear each flake that hit the wire then finally it just became a
rushing sound.

I ve been trying to piece together what everyone has been saying about it
with my own experience. So far I suspect that the weather must be fairly dry
just before the precipitation starts.
