[RFI] "New" RFI - solution?

Has there been any recent rain or even fog or heavy dew??  Moisture on
insulators that are dirty can cause lots of noise which will go away either
when it rains hard enough to wet the whole insulator or dries up long enough
for the insulator to dry out.

OK. This is really strange, but I ***think*** things are back to normal.

Yesterday, after we had returned from a meeting in a town about 30 miles
away, I began to gather all my DF gear to begin tracking this crap down.

While I was doing that and after checking that the +40 dB over S-9 noise was
still on 80, a bit lower on 40 and still very noticeable (+10 dB over S-9)
on 20, I was listening on 80 meters to it.

Suddenly, the character of the noise began to change, slowly tapering off,
to a series of crackles, then periodic pops, then....dead silence.!!!!

I was mystified. 

Now I suspect that either some animal or large bird, or perhaps a tree
branch, had gotten across the 13.6 KV HV power line running down our alley,
and it took a day or two for it to finally burn away and clear itself.

I operated as usual last night, and again this morning and the noise is
still gone.

Although I am keeping my fingers crossed, I am continuing to prepare my DF
gear for a possible return of the garbage.

My noise level is back to normal, and, so far, has remained there.
