17,2KHZ? Isn't that at the upper end of human hearing? Well within a dogs
hearing range?
thanks, John.

Hi John, 17.2khz audio is not audible to me because I am to old. 17.2khz RF
or electromagnetic radiation is usually not audible to anyone, even dogs. I am
sure if you were too close to a very strong 17.2khz EM field you could feel
something or hear the effect the radiation had on close in objects, but I don't
think you could hear the EM. Sound waves and EM waves are two different
things.
