Im of to test all the sockets, see if i can get to th bottom of this mystery.

Happy sniffing Colin

Might have to get one as I'm intrigued now

I bought a Belkin pf30 after my sniff experiments. No noise now. The telly looks a bit better and the sound seems to be different so worth while i think.
Even though the neighbours are on holiday i found no noise when testing at midnight.

What is the noise telling you?

Noisy mains?

Is there any difference between the pf30 and a Tacima 6way mains extension rfi/emi?

Hi Guys,
Just been re-jigging my system so I thought I'd make use of one of these Noise Sniffers and found some very surprising results (to me ) . My listening room doubles as our main viewing room so TV and Sky box etc. are on the same 'sideboard' as everything else.
I tried the Noise Sniffer on bog standard wall sockets around the house and found the noise intolerant (and going erratically off scale) at sensitivity 4 on most of the sockets. I then plugged in into a 'proper' hi-fi extension block (if there is such a thing ) which in turn was plugged into the Belkin PF30. Result: up to sensitivity 9 (max) and getting the odd crackle - brilliant, I thought.
Whilst I was doing all this the hifi itself was shut down completely, nothing powered up, but the TV was on, on a Sky HD channel. And then the adverts came on, and it began to crackle a bit more, particularly when the scene changed, some being quite noisy. I watched and listened, fascinated, and the changes in crackleing continued to coincide exactly with the changing scenes - weird, what?? At two or 3 points the quickly changing screen was predominantly red in colour, as you might represent a scene from hell, and the noise was intolerable again until the scene changed, only to return when the 'scenes from hell' returned.
I watched this until the adverts went off, several minutes, and there is no doubt in my mind that I was seeing and hearing a real phenomena and not just a series of coincidences. When the normal programme resumed I again got just the odd crackle at sensitivity 9 - the PF30 is certainly doing something, but what ?
Anybody got any explanation or fancy repeating the experiment?
Cheers,
Dave.
EDIT: I forgot to mention that the SKY box is plugged directly into the 'Always On' socket and the TV (Viao LCD) is plugged into a 'Switched' socket on the PF30.

Welcome back Dave but I still hate your avatar. It makes me feel sick.

With the sniffer on and no equipment switched on the noise jumps about like a police radio. I have a large fridge upstairs so could be the switching. Strip lights seem to make little difference. Not sure if the sound has improved or just my imagination but tv is better.
Tried the sniffer through my Merlin block and the same noise level compared with direct into wall socket. Surprised as i do remember the Merlin block and cables dropping the noise floor significantly when i first used it.
Looks like its better than the Tacima.
