I have no trouble with your checklist except #7. Like it or not, the FCC RE limits protect "I Love Lucy" broadcasts. More basically, the limits protect the broadcasters' market. If excess RE from consumer appliances interfere with reception in fringe areas, the broadcaster's customer base is reduced, which in turn reduces the value of advertising time that he can charge. You are literally putting him out of business, and he has a license to transmit and your appliance does not.
