Re: [IRCA] [NRC-AM] Need help with noise issue

Hello Patrick,

After having visited your residence a few times (and remembering the 
general location of your neighbors), I may be able to offer a couple of 
suggestions concerning your noise issue.

You can locate the general direction of the noise source by taking one 
of your portables (ICF-S5W, modified PL-380, etc.) outside at various 
locations, and using the portable's loopstick to null the noise source. 
When you combine these different noise source bearings at different 
locations around your residence, you can get a pretty good idea of 
where the noise is coming from. If the noise source  bearing always 
nulls toward your residence, I would temporarily turn off all power 
from the electrical service panel, and see if the noise disappears. If 
so, I would turn on each breaker switch individually, to see which 
electrical circuit is related to the noise problem.

Repeating the above procedure around your neighbor's residence (if the 
portable noise source bearing information points to his dwelling as the 
source) should give you the final evidence that you need to nail the 
problem, assuming that he will cooperate in playing with the electrical 
circuit breakers. The above suggestions are related to experience 
dealing with Longwave electrical noise souce isolation this past 
winter, during which almost all of the new Ultralight NDB-DXing 
fanatics found it necessary to chase DX in the freezing cold, in order 
to escape isidious indoor electrical noise.

73 and Good DX,

Subject: [NRC-AM] Need help with noise issue

As any of you know, I have lived out here on the Oregon Coast for most
of my life and at this QTH, for the past 30 years,  my noise level has
been almost zero most of the time. Well, earlier this week, I got home
and was turning across the band with a portable and it was wall to wall
buzz. I immediately went to the R8 and low and behold the noise was also
present there, but not as bad. All of my antennas get the noise, the
Eastern Beverage much less. Okey, I did a bit of checking and my
neighbor,  2 houses down has a new light in his carport is setup on a
motion sensor. I think his old one was also that way, but it never
caused noise. This is just a guess, unless he added something inside,
but this is out in the open easy to see.  Do the newer motion sensor
cause this kind of buzz? If so, is there anything I can do about it? Do
they make ones with filtering that do not cause noise?  Again, this is
just an educated guess and I have not contacted him as yet. The guy is
92 and has his house on the market, but this unit is permanent and when
he sells the house, that is included I am sure.
  A couple other questions. I can go throughout my house and the noise
is horrible on a portable. I like to lay in bed and listen to KGO, KKOH,
etc and I now have a buzz behind those signals at night. The noise it
extremely loud by my electric meter so it is radiating through our
underground powerlines. Is there any filtering I can get installed at my
meter or powerbox to filter noise coming down the line? Seems to me, I
have read about some filtering and does it work?
  When I pull out of my driveway in the van, 10 feet away from the
house, the noise drops out very quickly, as I get away from the house,
it drops even more.  so the big issue is the radiation through the
powerlines I believe. By the time I get in front of my neighbors house
that has the motion unit, I don't get much of it, but I am away from the
powerlines.
 My next issue is to replace my RG6 with Quad RG6 and that may help.
  Any suggestions?
Thanks.

73,

Patrick
