Another source of noise. Cheap LED lights. I already knew I had some others that cause FM radio and WiFi interference but these go to the recycle heap. In picture Lights on, Lights off, antenna is 30 feet away outside. The source of noise is often closer than you realize. A few people doing cw on 40! But i could have heard Spain ssb (from near Chicago) more clearly earlier. (No additional amplifier, just the Lime). Still on much clearer now. (ea1dlu nw spain , 150w ssb beam 27 m up)
