I've seen that a lot in the nineties, but it was always one of these

- bad power cable, usually extension cord which would be lying on the floor, yanked then fixed by scotch tape
- overall bad electricity in the house ("the house burned and they had to replace the roof but the wires were OK")
- bad grounding; in some places I'd measure 105V between the case and the null wire, and between the BNC connector and the ground as well.
- coaxial network cables lying on the ground and yanked by someone's heel (or hanging over a yard and pulled by a tall truck)
- electrical activity near a network cable (production plant, when a 20KW motor starts; welding, x-ray machines)
- someone borrowing a network cable while buffers are dirty (this one was in 2001, Texas). That was the last case that I remember.
