Topband: Ethernet Interference

[Dan Edward Dba East edwards]

 Trevor, for what it's worth, I have found that not all SMPS's (switch mode power supplies ) are the same; some of the small-ish wall warts  spray tons of r.f. hash, others, fairly quiet...one video cam supply was incredibly noisy here; i put a spare netgear supply on it, and poof, gone.. mind you, i'm talking 160m, here..
If it's easy to swap it out, might be worth a try, anyway...and lots cheaper than ferrite..
good luck, w5xz, dan

 I got rid of mine by winding many turns on 31 mix.First choke was right at very first internet box. And then at the pc. Also everything that enters my pc has 31 mix choke even the power cable.I still get birdies from washing machine and treadmill but I'll get to that sometime. DXEnginering has some boxes that has rj45 connecters on them. Never used them but plug and play. Fred KB4QZH
