[SADXA] Trico RFI Problem

On the afternoon of Thursday Feb 1st I sent an e-mail to Trico's Dave 
Walk (WL7BHR) to report RFI across 15m and some on 17m.   The noise 
peaked to the west, a square wave with distorted tops, whose pulse 
repetition rate stayed constant, 24 hours a day, it's been there for 
months. Dave came to the house the next morning and took readings.

I suspected either a close-in neighbor's solar system or the Trico 
transformer near the house where I heard the noise on a BC band radio. 
Dave had a Line Tech come out to open 2 transformers on the road and 
eliminated them as the source, although he could still see the noise on 
his scope.

For several days this week Dave drove around the area, he found a noisy 
TEP pole, and a noisy Trico pole.  Trico serviced their pole on Thursday 
Feb 8th, but the 15m RFI was still there.  Dave called me later in the 
day on Thursday to report he found what he thought was the true noise 
source out on Decker and Potvin, which is due west of me.

On Friday morning, Dave called to report a line crew is at the suspect 
pole and fixed an obvious arcing problem.  With Dave on the telephone I 
came up on 15, brought the antenna to due west to a quiet band.

Dave stopped by with a map that showed the poles he inspected over the 
week and location of the problem pole.

I've never heard of anyone getting this kind of service from a power 
company on an RFI complaint.

Cheers,
