3. AM radio interference on voice when DSL is on
I just bought a voice speakerphone/answering system combo and it doesn't get along with my DSL connection in a weird way. I can make incoming calls and outgoing calls on the phone, and the DSL connection and speed are fine. However: 1. When I'm using the speakerphone for more than 10 minutes or so, I start hearing a radio station in the background 2. When the answering system picks up an incoming call, it records only the 1st 3 seconds and then terminates, as if it did not recognize the call was active If I turn off the DSL modem, the answering system behaves normally and I hear no AM radio. I do have an inline DSL filter connected in series with the speakerphone. Before I bought the speakerphone, I used a cheapo phone on which I found I needed to put 2 DSL inline filters in series to make modem buzz go away, which was a bit perplexing but did not seem significant. Now I'm starting to think it may have been. The telco, dsl provider, and speakerphone technical support are having a grand old time expressing surprise and blithely blaming each other. I've googled and read a couple of hints on this newsgroup, but they seem to talk about 2 slightly different things: AM interference with the DSL connection itself (not my case), or RFI interference on a phone line from nearby AM stations (which ought to be independent of whether my DSL modem is on or not). I also found something about lines being "unbalanced", butI'm not sure what that means -- though I may become unbalanced myself if I can't figure this out. I do also have a fax connected (unplugging it does not help), and the behaviour is the same if I try a different phone jack. I'm in an old apartment where someone ought to simplify the wiring, but I'd much rather it didn't have to be me. Any suggestions... Thanks, Martin

7. Need Power Supply Info for ab exterbak USRobotics 56K Faxmodem Model 5686
I got this external modem as-is for free, without its power supply. I checked the documentation both on-line and printed, but find nothing to say whether it needs AC or DC, what voltage and how much current it will pull. Please help.
