Somebody suggested having a young person listen for a very-high pitched sound. I think that's a very good idea indeed. Has that been tried yet? I know a teenage boy that can hear the 'ultrasonic' noise emanating from most cell phone and tablet screens, and at a considerable distance. 73, Mike www.w0btu.com _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
