Steve,

I will be very interested in whether or not Xcel actually follows 
through and fixes your problem.

Over a year ago, a local Xcel RFI specialist came out to my QTH and 
identified not one, but three different poles that were generating 
significant noise.  He told me that a crew would be out in the next few 
months to fix them.  These poles generate S-9 plus QRN, mostly on 10 and 
15 meters.

I'm still waiting for them to come repair the poles.  They no longer 
answer their phones, and do not return calls.  I am currently working 
with the ARRL RFI desk to try and remedy the situation.  They sent a 
letter to Xcel on November 7th, informing them that they are in 
violation of FCC rules.

At least one other ham in the Denver area is also getting screwed by Xcel.

This has been a recent change in attitude by Xcel here in Denver.  I've 
had two other incidents of problems in the past with power line QRN, and 
Xcel fixed them both within a few weeks after I reported it.
