A few years ago, I moved to the inner city of my hometown after many years of farm life in the country. I saw these gigantic antennae with spiral bases on these cars and vans around the hood. Naive me got excited and asked if they were amateur operators, innocently hoping to strike up a conversation about their rigs. They got downright mean, vulgar, and in some cases threatening for simply asking that one question. After a while, I realized these were chowder-heads running high wattage on CB. Mornings and sometimes in the evenings, their ear raping interference comes through my computer speakers and my headset when playing video games. It is super annoying.
ETA: These guys know they are causing massive interference. They simply don't care for anyone but themselves.
