Those are good suggestions and I am going to do just that. I am a little suspicious of my DSL modem because there are no chokes on the cord to the AC adapter. It is strange. If I put an AM radio near the heavy ground wire that is connected from the circuit breaker box to the water pipe where it enters the house, I get almost as much noise on AM as I do when I put the radio near the line carrying the DSL signal. That ground wire is nowhere near a phone wire. I have unplugged my DSL modem stopping the internet connection and checked the heavy ground wire and there is very little additional noise then. I thought maybe what I was hearing was other noise on the ground wire, but it is definitely the DSL signal. I have been happy with DSL other than that.

If on a power line put it on the cord as close as possible to the power source. You may have noticed that the more expensive USB cables, audio lease and power supplies will have a ferrite choke on them. I had a buzz with my AllStar MicroHub. I had a ferrite choke that I think was on a Decktalk Express serial cable. So I opened it out and wrapped the cable about 2 turns and closed it back together. Because the thin wire wasn't gripped I didn't think it would work. But it did very well. Very useful to have some kickingarond. Be careful though, I just brought some and they are not hinged.
