radio we use

Hey, which radio we use. I rec a small FM one. Steven Gibbs uses a radio to find a vortex because it is easy. Simply wait for the radio to cut out and you are over one. This is better than the frequency counter method that he uses. OK for that method you look for a rise in frequency size. Better to ask the inventor why and how it works as it is a mystery to me.
