I have a Speedstrean 5260 DSL modem. I don't have so much of a problem on
20M, but do have problems on 40 and 80 m. I don't have the problem at low
power but only high power.
One thing both of us might want to try are phone line filters like form
K-Com. The problem is, I don't know what their frequency response is.
This is a good question for the experts on the RFI reflector.
