What Cisco router do you have? I have a Cisco ASA 5505, which is a fairly
standard PIX-class box. I have not noticed any noise, but maybe I just
haven't listened closely enough.
The 8-port router, DSL modem, wireless Access Point, and KVM-switch sit
about 2-feet from my Orion. I use standard CAT-5 cable and do not RFI
chokes on anything except the various power leads. I don't notice any odd
noises in the Orion.
Tell me what birdies to listen for and I will check to see if I am missing

I continue to battle the same problems here. I have a business-class Cisco
router without about a dozen unshielded CAT-5 cables connected to various
PCs and devices around the house. I just purchased a box of 0.750"
Fair-Rite #31 core material and the result is that router birdies are
somewhat reduced, but still very annoying. Half the battle with CAT-5 cable
is in getting enough windings on the core without running out of room.
Adding cores on the PC end seems to offer little befit, so it would appear
that the majority of the RFI source is coming right out of the router.
Any suggestions from here? Going to an all wireless WiFi network here is
not an option at this time.
