Check out the ground connection of the cable shield as well. My
groundation didn´t exist and caused very strong qrm.

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

'topband List' <[email protected]> Subject: Topband: Ethernet Interference Hi AllI
seen a post somewhere recently explaining that it was a waste of time putting ferrite on either
utp or stp Ethernet cables, I can't remember which, or where I read it, I am trying to remove
some birdies on 2m caused by home network,Anyone have any pointers, I have a large amount of cat
cable around my house so don't want to replace it with the wrong
type,ThanksTrevorEI2GLB_________________Searchable Archives: http://www.contesting.com/_topband -
