Topband: Help with RFI

[ZR]

Im running shielded CAT 5e from the router up in the office to the basement 
and none of the rigs bothered it but I did have to use a single 31 core at 
the router outputs to eliminate its noise; the 6 CAT5e cables are grouped 
together thru the toroid, and another at the DC input. The cable modem that 
feeds it was also very noisy and even outputting on the RG6.
