I had this problem in spades especially 160. In the end, after some number of repairs to AT&T cabling, etc, the replacement of a 2Wire 3800 gateway box with a 3801 killed it dead.
IF you have a 3800, it will need to be replaced, although the sudden appearance seems to sound like something suddenly gone wrong. Make sure all the little telephone plugs get exercised to clean them up and see if it "suddenly" goes away. In any event back in 2011 I was involved in a very careful staged repair, item by item to see what items made any difference. From my situation and about a dozen parallel similar extended careful replacement exercises, AT&T seems to have it solved and the solution is in their "book". So just let them do their thing. 73 and good luck, Guy K2AV On Fri, Mar 17, 2017 at 3:37 PM, John Saxon via Elecraft < [email protected]> wrote: > Off topic, but perhaps others have had the same problem. > I have a K3/100 + ATU (ser#3542), purchased as a kit in 2009. No problems with RFI until April of 2016. All of a sudden RFI on 80,40(didn't try 160). Been off these bands ever since, although all my buddies hang out on 40. Have had AT&T out 4 times, no help. > OK...I just found an AT&T Uverse user forum that discuss this very thing, same symptoms as mine, with a ham participating. If I am reading it correctly, they are saying that the bands that Uverse uses for multiplexing includes 160,80 & 40 frequencies. One of the contributors said that AT&T eventually upgraded his equipment, including replacing some twisted-pair cables with CAT5 cables, and it solved the problem. I am supposed to get a call Monday from an AT&T guy who is familiar with this. But I would like input from my Elecraft ham buddies. > Anyone out there experienced this before?
