I've got the same problem here especially below 1 megacycle. The noise also appears in the 75 meter ham bands between 3.5 and 3.7 megacycles. It could be anything electrical in the neighborhood- a motor, vapor light, controller, or anything that uses power; the higher the power the more noise. I gave up trying to find it.
