Ugh.....this is really annoying to say the least.
Yesterday I installed a good 1:1 iso balun at the feedpoint of my R5 to eliminitate the stray RF in my shack. Last night the RFI on 12 was so bad I turned the rig of.....now...today 12 and 20 are nasty.
Earlier today I shut off the main breaker and powered my ICOM with the 12v setup I use for camping. The noise was still there at 20+db. So I took an AM radio around the house....thinking I might find something.
Unfortunately I did....and its a nasty signal. I found a good EMR source behind my entertainment center.....about 4 feet off the floor. The only thing in that are is some 75 ohm coax running up the wall into my master bedroom and a phone line for the Tivo.
With the power off the RFI is screaming up and down the 75 ohm coax....but when I checked in the basement where the coax came in....there is nothing.
I havent talked to me neighbor on what might be on the other side of that wall....but then again how do I know whatever is over there is causing the interference in the first place?
Before I put this R5 up I had an Alpha Delta DX-EE that worked pretty well running above the roof at about 10 feet. I never had any RFI issues with it....and up until a few days ago....before I installed the balun...I didnt have any issues with the R5. Could the balun be contributing to this problem?
I made a short video of my ICOM display with audio of the signal. You can see it very clearly on 12 and a little bit on 20.
here is the link to the vid...its about 45 seconds long.http://www.flickr.com/photos/cerberus314/2642829418/
