[RFI] Line noise

[cqtestk4xs at aol.com]

I thought I had posted this but apparently it didn't make it...lost in cyber-space.  Let's try again.
When I bought my land in Belize my location was totally quiet.  In the past three or four weeks line noise has come up.  Located the pole which was the cause.  The power company has been out twice to fix it but can find nothing wrong.  The have inspected the pole, checking the usual things...loose connections, bad arrestors etc and could find nothing.
However, there is a drop from the transformer to several meter boxes below it.  They are all in one big panel box which the power company will not open to inspect since the panel box is not owned by them.
The RFI is as strong at that panel box as uit is next to the ground wire of the pole...very nasty.
Could there be something in the meter box (connections etc.) causing this.  In order to have them open the box the owner must file for a disconnect, which iof course means $$.  Then the owner will need to have an electrician inspect and tighten...again $$.  Of course the owner will not pay for this so I will have to.  
One other thing I forgot to mention...sometimes, like today it is way down, other days it isn't.  No special pattern.  Some rainy day it is bad, others it isn't.  Only discernable pattern is that it occurs a little more often in the daytime...but not much more.  Today it is only s-0 to S-1 without the preamp on.  On bad days it is S-3-4.  Measurements are on 10 meters with the antenna facing the pole.  Of course it is worse on 160 and 80.
Question...Is it worth the time and money to do this?  Things are quite a bit cheaper in Belize.
By the way, the two buildings that the meters are connected to are electrically RFI quiet.
Any thoughts?
