Sorry but you don't know what you are talking about in this matter. If you ever attended any international giant scale aerobatic fly-in (like the 3W show, which I have) you would see many 3W factory pilots flying other brands of aircraft. It's very common. The two gentlemen who own and run 3W were not there (I know them also). The radio station was transmitting from a remote site on the airfield so again, you talk out of your rear end.

I have associates who were at the event and witnessed this unfold so while my information is factual and correct, you have no idea about what you are talking about.

The news report said he was an engine and airframe manufacturer...and it says 3W on the tail, you don't see engine manufacturers flying somebody else's brand in demos, and the news told where in Germany he lived, so it's not really a big mystery to most to figure out who he is. Does not really matter, though.
As far as the "local pop station" being the culprit, I seriously, seriously doubt that. It was rather sudden interference(if it WAS interference) I don't know of too many radio stations that suddenly switch on during the middle of the day. While it is possible, it's rather doubtful, I think it would be better to wait for more facts to come in before accepting such a conclusion.
