Has anyone seen this ?

This noise started about 45 days ago. un hooked antenna and its gone, so my thought is its coming in through the antenna. Will do the power shut down when the warrden is not at home, any ideas?

Pretty definitely a switching power supply of some sort. Have any neighbors installed solar panels? The inverters will also do this. The first test is to pull the main breaker with the flex receiver powered by battery, ups or whatever is available.

Thanks Mike, my 160M is quiet except in summer when the AM radio station about 12 miles away gets going on the medium wave towards europe.

Yes, probably external to the house. There are some devices that appear to be off but may actually may be on.

Evening john, disconnected whole house at the meter. No ups on anything, phone line may have a few volts . Cordless phones work off wall worts which are without power. Only solar is three blocks away and they are grid systems . I will just have to go hunting.

I found my phone wall wart was causing similar issue.

With the power off???

I killed the power to my house and property so I could eliminate the possibility that the interference was caused by my house. It is definitely off site. In the process of logging time of day, start/stop so I can narrow down what it may be.
