[TowerTalk] Noise

[w4lde]

If this question is inappropriate for the reflector I apologize but as 
of last Friday I started to experience significant noise (S-9) on all 
bands from 160 through 15M with the lower frequencies much stronger.  I 
thought that it was due to power line noise but it appears to be 
intermittent in that it completely disappeared last Friday evening but 
once again showed up last Saturday and stayed this way.  On the Ft1000mp 
the noise blankers are completely ineffective.  At the same time I 
started having internet problems and the cable company indicated they 
should have the speed issue fixed by Tuesday.

The cables are run on poles until they enter a subdivision which then 
run underground.  My question is can cable lines be the possible problem 
to HF frequencies?  The power and cable companies have been installing 
new poles and running new lines in the area which initially led me to 
believe it was a power issue however, while I was writing this email the 
noise completely disappeared for a few seconds and then reappeared.  As 
I was looking out my window I noticed a cable company buck truck  
through the woods towards the main road, I am off now to talk to them 
and see what I can discover.  Any suggestions?

Thanks for the bandwidth if this question is inappropriate for this 
reflector.
