Sounds like an electrical security fence.

I have also ft2000.and also the same noise!
I receive this noise only when antenna is connected, this noise does not come from my house.
You have found then the source of the noise?

Try getting rid of other electronic devices around the radio till you find the culprit... as someone else suggested it's probably RFI off a DECT phone or a phone charger. You might to switch back to an analog or hardline phone if you can't isolate the noise.

Hi,
first of all congrats, that this noise has disappeared from your shack. I have the same noise here. It comes from my DECT phones. Noise only appears, when the phone is connected to the docking station. So it might be the battery charger of that station.

As others have pointed out, it sounds very much like a switch-mode mobile phone or battery charger.

F8BBL put all of the plugs of all your electronic equipment out the wall and check if the noise is gone, and give us here the solution so others will learn.

This might be BPL (Broadband over Power lines) This seems like the power companies testing BPL?
