[net.general] non-TVI

goutal (10/29/82)

The good news is that your neighbor may not be suffering from true
TVI.  MY home terminal and my home machine both put out quite a
bit of hash that shows up on our TV set downstairs.  Come to find,
it's NOT being transmitted through the air, it's the power supplies
juggling the power mains in my house, which uses rather old wiring.
The solution, they tell me, is to buy a cheap little filter to put
on the outlets where I plug in my computenmachinen to smooth out the
backflow.  I haven't gotten around to choosing one -- my interim 
solution is to not compute during Sesame Street, which is not too hard
(note time, above).  It's just possible this is what's messing up your
neighbor, being in the same building and all.  Dunno about the legal
implications, but if this is the problem, it would seem simply prudent.
