The title says it all, Ethernet + ham radio = noise all over many bands, HF to VHF!
I have S6 to S9 of noise from my ethernet which affects 20M and even up to 2M!. I'm still trying to find out if there is a definate source, or if it's all from one or two offenders.
Basically I have fiber optics to my home --> then ethernet to a router/firewall/wireless hub ---> then a line to a 1Mbps switch which has eight ports on it, 1 goes to the router, each of the remaining 7 go to different rooms in my home.
Shutting off the switch kills most of the noise.
Previously I was proud to say I have a hardwired home (great bandwidth, gigabit speeds), no need for wireless except for when using a laptop on the couch or on the back deck.
Now I almost wish I went totally wireless!
So if any of you are starting to play with ham radio and notice that the noise floor is too high (especially on 2 meters), try shutting off your ethernet network and see if the noise floor drops!
I have a bunch of ferrite filters that I've been saving for years, I guess it's time to see if they will solve this without killing the ethernet performance.
