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

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:
