I live near the Atlantic Ocean in "Slower Lower" Delaware. Our problem here is that during dry weather, we get salt spray on the power lines and transformers, leading to all sorts of noise. A good rain helps.
I have a small Yaesu VR-500 wide band receiver. It works very well for tracking down RFI/EMI around the house as well. Good way to find offending "wall warts," and the like /paul W3FIs
