Nothing to do with the long clip lead on the end, as I demonstrated. Regular issues with long ground clips at high frequency is another problem entirely. You can have the best and shortest ground clip possible and you'll still get this effect, picked up by the probe coax. And the latest video shows you don't even need the cable connected at all to get a response. Enjoy.
