Fact 1: Installing a 2 meter bandpass filter will not help in the slightest.
Fact 2: I have a house full of LED bulbs that put out NO noise on any frequency (Cree brand)
Fact 3: You must find the noise at its source and eliminate it. Start by flipping the main breaker to your own house. Shut down the entire house, including anything that is running off of any UPS. Shut down EVERYTHING. Is the noise still there? If not, praise Jesus. It is in your own house. Something you can do something about. If it is still there. You are in trouble. If it is gone, start by turning OFF every breaker in the box, and flip ON the main breaker. Still gone? Start flipping on the breakers one by one until you find the breaker or breakers that cause the noise to return. Now go to the room/rooms that the offending breaker powers. Start disconnecting everything in that room until the offending device/devices is found. Take a hammer to that device, and pulverize it until it is no longer recognizable. It goes without saying that you power the rig from battery during all of this time.
