[BC] Power Line Noise (was: BPL)

[Tom Taggart]

My friend and former business partner has been playing with a neat device  
made up of an ultrasonic mike & "downconverter" to locate noisy poles.   
He's works 6 sideband, mostly (call: KB8ZMJ) and of course the noise  
drives him crazy. Allows him to narrow down most noise sources to the  
particular pole which he can then report to the power company.

Local troubleshooter for the power company is very cooperative--when his  
supervisor allows him to be.  Device located a pole recently where two  
feeders crossed at right angles on the same pole.  There was an small arc  
that had been slowly burning away on the pole under the cross bars.  The  
pole was about ready to break in two.
