[ADXA] Solving power line RFI

[Ken Personal]

Jussi … you probably already detailed it and I missed it, but what piece of hardware on the pole was the issue?  (Arrestor, insulator, jumper, regulator, transformer, etc). Thanks and congrats on getting your noise problem fixed !!

When 80m was very very quiet, I could sometimes hear it there too. As the wire got thinner, the noise increased - it was already S7 on my inverted-L (it started around S5).

There is one minor issue remaining that I can weakly hear on 10m but they have confirmed the presence of noise at that location but still need to use ultrasonic dish to locate the exact source & fix. They will look into that next week.

As you can see there, I was not able to locate the exact pole(s) but only give them the approximate location of the RFI. When I submitted the letter, I got the to sign a copy of the front page acknowledging that they have received it (paper trail).

I confirmed that it was and then they said that check again in about 30 min. After that the 160m noise was gone: they found it and fixed it (photo of the trouble maker attached). Arcing had started eating the wire (brownish area).
