[Yaesu] Good rigs for power line noise

[CBoone@Earthlink.Net]

As a former Sr Telecom Egr/Tech for a major public utility,
I can possibly help John....
1) If contacting the company directly (in writing preferably),
see if they have a telecom or radio department....there may be a
ham in that dept..if not, at least they will know RF....sometimes
the job of TVI/RFI is given to the line dept....I would REQUEST
in writing that a person with knowledge of RF supervise the work!
2) If no action is taken, then write them back...inform them that =

under FCC rules, they are REQUIRED by LAW to clean up the problem.
cc: Riley Hollingsworth of the FCC and make sure they KNOW you cc:
Riley! :)  Also carbon the state PUC/PSC...that usually gets them
moving!
3) If still NO action after a reasonable time, get FCC/Riley directly
involved....they wont back down to him...

BTW forget a "good radio for noise"...you CANNOT defeat noise at
the rcvr...you MUST get fix the problem and get rid of it at the =

source! Noise Blankers, etc can only do so much and usually are
good for natural background static around 30-70 MHz (lowband VHF)...
where of course it peaks around 6mtrs! But for electrical noise caused
by bad insulators, loose ground wires, ground wires touching or close
to energized/electrified parts, etc, you HAVE to fix it there...

If you have a portable AM radio or a yagi on HF, try to get an idea
on where the noise is coming from...AM portable are bi directional
with the ferrite rod antenna inside...take a couple of readings at
different points and then where the lines all intersect, thats your
source...I have used such in the past on some TVI issues...if the =

noise on HF sounds like a BURNER (heavy grunge almost like a ckt =

burning in two) rather than light white noise or static, you might =

check the poles at night..look for a flash or arc carefully on poles
within 2-3 miles of your QTH....Do you know the voltage of the
distribution? 7600/13000 lines (which usually use smaller bells and
insulators and are spaced closer together between the conductors)
usually do not burn but have a constant buzz or hiss...
higher voltages like 20Kv single phase/34.5-35KV three phase have
larger bells on the insulators, BIGGER lightning arrestors and
if the (ground) wiring in the field near the conductors is not =

done right, can actually BURN when dry...but the noise will go
away on wet days....(not always the case with the lower voltages)

Hope that helps somewhat...I did 12 years with a power company and
was the primary RFI/TVI guy in the department....and worked MANY a
problem on such issues....(talk about some overtime! :)...
Its an art finding and fixing it...but it CAN be fixed...and MUST
be done at the source...
