Possibly powerline noise (QRM) (RFI) still at KA4UDX, shot this video today 02-18-2010. Please excuse the “shaky cam” as I was hand holding the camera.
You’ll notice it starts down at 80 meters (probably lower as well) and I can find it all the way up to 6 meters into VHF (50 / 51 Mhz). It definately has a pulsing but random nature to it which has been seen here before and seems to match up with some piece of powerline hardware dangling in the wind and having a good “sparky” and arc’y at a nice high voltage level. I hope that isn’t the feed to someone’s business or home.
Anyway Florida Power and Light is supposed to have the latest RFI report / hardware broken problem found – thing fixed by this week. So we’ll see what happens. Maybe this is another one.
