Widespread "sizzling" interference on 75 meters this evening

[w1vtp]

Well Rob, interestingly enough, right around that time Ken and Garrett were outside testing a jacob's ladder they built.  Coincidence?  I think not! LOL

Put Ken back in the closet!!!  

No more ladder stuff. Have him build a 48 pill "E" rig

This "sizzling" sound reminds me of low density sferics present at VLF.

Here's a NASA recording:

Which can be found on this page:

Can this event be some kind of high density sferic associated with the recent tornado outbreak? Was that weather in the area at the time? Just speculating.

or use the class e rig to drive the ladder

    KK4YY,

    Your the first one here to pick-up on this...  You hit the nail on the head !

    Go back to my initial post in here (reply #9).  It explains why the sizzle had
    such a broad front vs the point source of the twister signature...
  
    With a "nest" of twisters the signature gets broader as witnessed with the
    system we had when the noise was heard this past weekend.  Just a
    tremendous amount of static electricity bouncing around within a very nasty
    weather system several thousand miles long...

    No man made mysterious data system or spread spectrum or new Doppler
    Radar etc however, yes, it  did a bit of natural spreading as it covered from
    below the MF BC band to well above 7.5 Mc...

    Some one mentioned the signature noise of a Tessla display.  Basically the
    same, as that device generates tremendously high potentials the same as
    the weather systems that generate enough static potential to cause lightening
    discharges many miles in length... You will hear the build-up before the flash
    on a Tessla Generator both on a radio receiver as well as audibly standing
    close to the generator.

    Oh, and by the way, welcome to  AMfone net Forum...

There is a particular type of "tornado static" I have noticed for years.  Instead of discrete crashes, it is a constant sizzling noise.  Reminds me of rain static heard on a mobile rig when you are driving along at high speed during a rainstorm.  I had noticed that many times when I would hear that particular brand of atmospherics, the next day there would be reports on the news that somewhere, maybe hundreds or even thousands of miles away, one or more tornadoes had struck. A few times, back before the days of instant news and internet, I amazed people when I correctly predicted that tornado activity would be reported in the news that evening or the next morning.

We had severe weather last night, with straight-line winds reported to be close to 80mph.  No damage here, but I didn't even try to  get on the air, and the  computers were all unplugged.  According to Vaisala, it looks like we are in for something similar again to-night.

I believe that 75 meters is actually a series of tubes, functioning in the ionosphere to pass along messages from one station to another. The Ionospheric Sounding project and the SIZZ-O-LEEN effect appear to be disrupting the series of tubes at times, and this cuts into Terry's high frequency response. Completely intolerable I say!

Go to 2:33 into the video.

Hah! That "takes the cake" Don! One of the best things about YouTube is that his stuff is archived there to keep the whole world from taking itself too seriously. Wish he was still with us. We could all use a few more laughs each day...

  The sizzle was back this afternoon...

  From  about 4:55 to 5:05 PM EDST, it built from a low buzz to a crescendo
  then died away... 

  Heard it on 3733 while I was listening for activity from someone on the WFD
   thingy... No activity but bet there was a small twister somewhere close by...
