[RFI] Local noise - another report.

[Tom Thompson]

Ken,

If you can get a fix on your predominant noise, your best bet is to walk 
in that direction with your loop.  If health reasons preclude this, just 
walk as far as you can and start from that spot the next day.  I have 
found that walking is far more productive than driving because you get 
some interaction from the car and the car is continually changing 
direction.  If you are distracted by other noise sources, ignore them 
and keep going in the direction of the predominant source.  I know what 
you are going through.   I have had weaker noise sources get louder when 
I got close to them, but then the predominant noise source takes over as 
you leave the vicinity of the weaker source.

Keep at it; you will get there.
