[TenTec] ? Electric fence noise

Well I don't see that as being "the way it is".   Yes the FCC has been 
operating with greatly reduced staff and available facilities.  They 
aren't allowed in their building due to current COVID restrictions.    
Yet, if you will read QST or other reports, some hams have received 
notice of violation for deliberate interference, excessive bandwidth, 
failure to properly ID and such.

Noise issues do require a lot of investigation and gathering of data.   
Usually it is initially up to the operator to either gather the 
information or at least enlist assistance in gathering the data.  Then 
contact the offending party.  Usually this has proven to be successful.

Power companies have been operating with reduced staff's for various 
reasons.  Some have resorted to contracting out services for 
right-of-way maintenance.  This causes limbs to remain rubbing against 
lines and poles.   As long as the "lights are on" the power company 
doesn't receive complaints.   I find they do act on complaints as long 
as the complainant  has shown good faith in the matter and is just not 
calling and complaining.   Thus the efforts one receives is mostly 
related to the effort given to the issue. Just sitting back and 
complaining has not been productive.   In fact it is usually counter 
productive.

So what have you done to improve your situation?    Nothing? Then that's 
the results you've received.

I have a farm in our area that moves his fence to graze different areas 
of his pastures.  In some locations I get noise, while in others, no 
noise.  I contacted him about it, explained my observations and asked to 
be allowed to walk the fence.   I found weeds against the wire in 
several places.  I returned with my string trimmer, eliminated the weeds 
and the noise was gone.   So a bit of professionalism, a bit of work on 
my part and my location is now noise free.  As to the farmer, it 
required no effort on his part and he was happy to know the issues was 
resolved.  A few weeks later he came back to me asking if I could assist 
with his off-air TV antenna?   Yes, I did and when finished he was 
impressed.   I was then rewarded with a couple of really nice sirloin 
steaks.   Nothing like good grass fed beef.

In my experience, most cases of electric fence noise was caused by defective insulators or corroded connections and thus the responsibility of the fence owner to repair. Most were cooperative as it was probably noising up their radio, TV and phone service.
