If you repeat the test with the breaker switches off killing power to the dwelling,
Great idea! 
high pitch sound/ noise

I would be absolutely shocked if the Ebtech Hum eliminator made any difference whatsoever to your problem. As far as I understand it the Ebtech is a transformer based ground loop eliminator. It electrically isolates one device in the chain from ground via a transformer. Definitely works for ground loops (I have a Palmer and an ART version of the same thing and they work a treat) however, the problem can't be a ground loop if you are getting it with a battery powered amp which isn't grounded.
When you walk out the house the noise seems to stop (or at least significantly decrease) then it reappears when you renter the house. That suggests to me that it is airborne interference from something inside the house. I'm no expert of this type of thing though so you will need someone else to help you actually find the source.
Well if it doesn't work he could always return it as he stated.

I know but since it can't work that seem like wasted effort time and money even if he gets a refund.

I run thru an Ebtech regardless of my location and I rarely catch a buzz unless it's of my own doing.
-
I don't think its a waste of time to try it. If it works all well and good. It was just a suggestion.

I suppose anything is worth a try when the problem is driving you mad like it clearly is for the OP. However, I just can't see how a transformer isolation box which breaks a ground loop can solve a problem that still exists with a battery amp which literally has no ground attached.
They are great little devices in the right situation. I know what you mean about them working with your Recto. I had a massive ground loop issue with my old Triaxis and pedal board running 4CM. Those isolation boxes are an absolute must in such a situation because the signal has more than one path to ground. I couldn't bear it without them for that rig. I just think this has to be different as there isn't even one path to ground let alone multiple paths if its still there with a battery amp.

I'd at least first do what 'Sludgie suggested and kill all power to the premises to see what effect that has.
Always best in life to tackle causes first before symptoms, if indeed the latter's still-necessary failing judicious exploration of the former... IMHO.

edited the title.

I think this is definitely some kind of interference from an outside source that is being picked up by your guitar. Reminds me of Joe Satch's Flying in a Blue Dream, where that little boy's voice right at the beginning was some kind of show that was picked up on Joe's guitar.
Did you try shielding the cavity? Also, try a different kind of cable, something well-shielded.
Since you have a battery powered amp, try this out in a different location and see if there's any noise.

Wow, didn't know that! Funnily enough, I pick up the radio when playing at home quite often, as there is no earth on the sockets in our bedroom (I reckon that must be why, anyway).

yeah that would make sense , but when i'm 15 feet away from my door the sounds stop. My other guitar i let it shielded , same problem
and i used different cable all expensive brands , vovox , planet waves..I need something that can filter out that anoyying freq . Like a highpass filter .

The joys of CD liner notes -
@Foxbilder i think you need to kill the problem at source rather than cover it up. Unfortunately,a high pass filter is unlikely to be the answer. The frequencies you are having trouble with are so high that you would end up filtering out a hugh chunk of the guitar sound with it. I suspect the end result would be like playing through a tiny portable radio at best.

Tried this yet?

Might be time to move?

wel this morning the sound was gone as you can see in this vid :
then later at 8:30 it returned .
So must be human that puts tv on , or boiler ... i don't knowhttps://www.youtube.com/watch?v=dpol7_YJSxk&list=UUUK5CXyeYo...1xZvCDEvPA
Perhaps, but is it being transmitted through your power wiring? You mightn't need to be plugged into it (I know you've tried battery power) in order for your gear to be affected by its EM field.
Again, as 'Sludgie and I said earlier, I'd switch off all power to the premises and see what happens.
