[RFI] Thanks to W9ZRX for passing this along - Wall Wart noise alert

[Tim Duffy K3LR]

I had a nasty noise of s9 plus for a week or so.  Finally tracked it down to

the wall wart on my XYL's sling box.  It had been there for years but I'd 
noticed it had always been warmer than most of them although it seemed to 
work okay.  Apparently, it must've gone bad and started generating a 
terrible hash.  When I pulled it the problem was immediately solved.  73,
