[RFI] RFI Digest, Vol 203, Issue 15

[Wes Stewart]

 I'm friendly with the RFI sleuth with our local electric coop (also a ham).  He tells me that ground level ultrasonic sniffers are pretty worthless.  Any physical obstruction attenuates the signal, according to him.  They do use one but on a hot stick where it can sniff up close.  Unfortunately, it's a union shop so he can't do it and has to have a line crewman do it.  The logistics of this are really detrimental to efficiency.  (Unspoken opinion of unions goes here.......................................)

Use of an ultrasonic detector is highly useful in finding discharges on the
electric distribution grid, especially localized to the home neighborhood.
Sure, MFJ makes one, but there is an option I ran across on the AirSpy
group.  if you have a Discovery (or R3 modified HF+) from AirSpy, you have
an ultrasonic receiver.  Have a view of the following link:
