RE: Throttle flutter with motor running, radio on
TimBle, I also spent well over 30 years in instrumentation in the aircraft and spacecraft field with some medical instrumentation and I can guarantee you that metal to metal vibration can and does create a great deal of RF that can (and often does) interfere with electrical measurements. Any time that any action occurs that can excite the electrons in an atom or molecule, you can create electron flow which can create an electrical field that can cause interference. I've personally witnessed this hundreds of times.
