So .... are you gonna get someone out there to fix your problem or not.
Call D* and get them out there to isolate the issue.
And fix what? replace his IRD.
I gone out to peoples home, went and changed the ground block, walk back into the house and they tell me "Well that fixed the problem".
So unless it noise coming through power since cable doesn't use voltage I feel it will be a wasted trip.
Just cancel and go back to cable.
