Hi,
For a while I couldn't figure out where the vibration noise was coming from. In the attic? A mouse maybe? I searched and searched for a source but could never really pinpoint it. Until one day, months later I was standing outside my house.
I heard it clear as day and I was standing very near to the little black box that the phone line comes into from the street. Short bursts of vibrations coming from the telephone line lasting 1 to 2 seconds. It's happening all the time.
What is this? It's been going on for years. And is it normal?
Thanks
Steve
