Some of you had requested I follow up on my findings here in the  
Boston area.

And, thank you to all for the tips and suggestions.

NStar did come out last week with their Radar Engineering VHF/UHF  
gear with a yagi for pinpointing the noise. The noise was so high  
along the power lines they could not pinpoint a specific pole or spot  
unfortunately. Not sure just what this means. So, their next step is  
to upgrade the grounds they found that were below spec.

Interestingly, just after they were out we had a light, wet snow and  
the noise quickly all but disappeared for about 15 hours and then  
quickly rose back to previous level. This has happened each time we  
have had a storm. This last snow was so light  and the noise  
disappeared with the first few flakes it is hard to believe that  
helped, but there was a big rise in the humidity? I would assume this  
indicates an out door fault, given the correlation with snow?

There was a very low level of noise coming from the same area, but  
did not have a chance to get back to check it with the 440 Mhz RCVR,  
but will be ready next time.

Stay tunedand thanks,



Was thinking about calling our volunteer fire Dept to hose the poles  
down given we don't use hammers, but.......Just kidding
