The box you describe is the 12 volt "filter" for the power. It contains 3 large capacitors (be careful, short one and it'll knock you on your rear -- big time). While capacitors can "go bad" -- it isn't likely.

Part of the 12 volt system is "filtered" (passing though the filter) and part is not. It is vital to make sure that the radio is wired into the filtered electrical system. Also, make sure that there isn't something wired in that crosses between the filtered and non filtered power source. (This is a matter of tracing out wires to ensure they're where they're supposed to be.)

However, fluorescent lights (particularly ballasts) can generate RF signals that directly interfere with the radio signal. This is more frequent as the ballasts degrade over time.

So you may need to "do" something about the fluorescent lights directly rather than a filtering problem. A radio shop may have a filter for the antenna wire -- or shielding -- that might solve the problem.

Under one of your couches is a electronic filter. That box is about 6 inches by 6 inches by 12 inches long. The older coaches had boxes larger then that. There is just one cable going to it. I suspect that in that shielded cable are 2 wires. I never took it apart and it weighs about 30 pounds. Yours may have quit.

My radio in the front had static in it from the florescent lights. I installed a new one because I wanted a HD radio & it still has static in it. The old radio in the bedroom which is original equipment. Is there a suppressor for static some where up front that went bad?
