Re: Buzz on my land line. Not due to DSL. Probably ground loop? I have that buzzing on my phone line seems like every year (been here 16 years). Every time I call, they say that it's probably inside and when I say I checked everything out, they come and the problem is on the pole across the road. Every time it's the same thing at the same pole, so now I just do a cursory check to say I checked it out.
Last week it rained for a couple days and the buzzing started up again. When I called they came out the next day and went straight to the pole.
