Bill, You are correct... I mentioned that ultrasonic recvr earlier in my
post. Trouble is a lot of power line noise / RFI investigators don't have
them. Those that are serious about finding the noises do though, as you
pointed out they can help find the actual components responsible. - Mike

Subject: Re: [TowerTalk] static noise
An excellent tool for finding sources of breakdowns in AC line
components is an ultrasonic receiver. These devices have a pick
transducer and the signal is mixed with an oscillator to bring the
noise into the hearing range. I have seen commercial units for very
low prices, and I have experience with homebrew receivers.
I used this technique (along with the sledge hammer) on many
occasions to isolate hardware, lightning arrestors, insulators and
splices that are arcing at very low level. They ALL make ultrasonic
noise when frying.
