I have witnessed radio intereference, and when it happened, it was obvious that it happened. During a contest, one experienced participant was flying without having the channel pin. A beginner contestant was preparing for flight, had the pin, and turned on his radio. The result was immediate and fatal to the experienced contestants plane.

On a second occassion a few weeks ago, I was flying my CAP 232, and was making a slow downwind leg to set up for an approach. Iwent to bank the plane right, and it banked left. I immediately called out "Radio Hit", chopped the throttle, and the plane nosed in from about 100 feet. As I continued to replay the incident in my mind over the next week, I realized that the problem was actually a stall induced by wind shear (also known as a gust of wind from the tail). In the few seconds, I had to react, I reacted improperly. What looked like radio intereference was actually pilot error.
