Jack is correct.
My first experience with this was as a young Novice licensee. I had a BC453
receiver connected to some type of wire antenna and had the bottom cover
removed. There was a dry desert breeze blowing outside. The BC453 had an NE2
neon bulb across the antenna input and it was blinking about once per second.
Today I put 10k wirewound 10W resistors across my antenna feedpoints unless
they are naturally DC shorts.

Here in Louisiana we get a lot of rain and thunderstorms. Operating during
rain used to be a huge issue caused by rain static. As the rain drops fall,
they pick up a static charge. When the hit the antenna that is transferred to
the antenna, and is heard on the receiver as an increasing buzz. Eventually the
charge builds up to the point where it exceeds the level where the receiver
protection kicks in, we get a quick “bzzzzt” then the noise is gone until it
builds up again. This is the static that Wes correctly refers to. I first
experienced this in the Clearwater, FL area many years ago, and before the
arrestors I experienced it here regularly.
