[RFI] Finding noise source

[Michael Cornwall]

	I found that the station antennas were not enough other than to
point generally the direction.  I do my noise-hunting on foot with a 2m
arrow antenna (a 3 el handheld yagi).  That way I can pinpoint the source a
little more finely.

Subject: [RFI] Finding noise source

For a couple of years now, I am suffering from terrible noise at my place
which covers pretty much all HF bands when it's on.
You may listen to it here: http://www.rigexpert.net/noise.wav
The noise seems like a power line one, and it stays on for days, but
sometimes (very seldom though) when I listen to the bands in the morning
before going to work, the noise is not there, which makes me think that this
might not be the power line noise.
I can easily determine the direction where it's peaking from - my
neighbour's house, but this is also a direction to the street power lines.
Since I only have one tower with rotatable beam (TH6DXX), I decided to built
4 element 2 m yagi and try to determine the bearing from outside of my front
yard, using IC746 radio on 2 meters. But, either the sensitivity of the
receiver on 2 meters is not enough, or the noise itself is not strong on 2
meters, I can not tell by looking on S-meter, where the noise is coming from
- S-meter stays on "0" all the time though the noise is still audible.
The question is, what would you recommend me to use as a "noise finding" 
device? I don't really have enough time to build something complicated. I
have to find out either it's power line noise, or the one coming from my
neighbour's.
Thanks in advance for the tips.

Yuri  VE3DZ
