Re: Telephone line interference




-----------------------------------------------------
In the UK, British Telecom supply interference supressors to be fitted on
incoming lines, I forget the part number. I am sure other companies can do
the same. The units are sealed, so I don't know what's inside, I suspect a
combination of L & C. Here I have looped the incoming line through a large
ferrite ring (ten turns).
