Not a dumb question about the splitter. If you have a passive splitter, one that does not require power, it is unlikely that it has gone bad but don't rule it out either. I would look to any active devices first, ones that require power to work. Like any boosters in-line. Tell me how the switch to the satellite dish works. It sounds like it can make things better when you activate it. Maybe try bypassing that first before you mess with the splitter.
This radio station may really be the total cause of the trouble. Can you hear what station it is? Is it an FM station? To hear this station on your TV means it is a VERY strong station. Being that strong it is very definitely getting into your system and causing an overload and causing the AGC circuits in your TV to do strange things. (AGC stands for Automatic Gain Control. This circuit 'sees' the strong FM station and cuts back the signal to the TV) If it is an FM station you can get a inexpensive FM filter at radio shack. It would still be a worthwhile test to run the cable directly to one of the TVs.
Questions: Has your system worked good before this location?
Is neighbors working OK.
