I changed TV & Internet providers from a coax feed line to cat5 feed line
from the point of entry at the house to the modem inside.
My tower that I load for 160m is 20 feet from the entrance point. Every time
I transmitted, 1kw on 160m, my tv would go down along with the internet.
It would reset a minute later. I never had a problem when the feed was coax.
I read K9YC's 'Understanding and Eliminating RF Interference' guide and added a
15 turn Ferrite choke right at the point of entry into the modem. I have
multiple
cat5 cables going to other computers from there. It completely solved the
problem
and the tv has no interference & internet is always on. Thanks Jim.

OK, gang, I need some different help here.
I have a 4 port wireless router (Trendnet TEW-812DRU at the moment)
connected to our main computer and two others in the home, not including
the laptops that connect to it periodically.
I have replaced the router at least 4 times over the past year or two due to
the fact that RF from my ham station is getting into it through one or more of
the three CAT-5 cables I have connected to it.
I have installed several of those snap-on filters on all three of the CAT-5
cables which connect to it, and also on both ends of the DC power cable,
making seveal "loops" through each filter.
I still wipe out the router every time I get on the air. I have destroyed one
$169.00 router, and two less expensive ones, a TPNET and a Cisco.
The only solution I have come up with is to disconnect the CAT-5 cables (all
three of them) from the router each time I get on the air.
Has anyone here had a similar problem, and if so, what did you do to fix it?
BTW, one of my CAT-5 cables runs to the ham shack, where it connects to a
dumb 4 port switch...
This has become a giant PITA.
Any ideas?
