  • I used shielded and properly grounded cat6, and even then I was seeing spurs and noise all over from 2m down. Granted the cat6 run was basically parallel to my attic antenna just about 5 ft from it for nearly the entire length.

    I put one ferrite ring on both ends of the run with 5 turns through each and nearly entirely killed spurs I had been seeing all over the spectrum.




















  • It doesn’t have as much to do with where the network stack is running, but that they’re leveraging hardware offloading. Their CPUs generally aren’t powerfull enough to switch packets at gigabit speeds let alone on many interfaces at gigabit or multi-gig speeds. Its by leveraging ASICs and maybe even some using FPGAs for hardware offload that they can switch packets at line rate. I understand how they do it, I still just find it kind of weird and cool.

    I didn’t list HDDs as someone else had mentioned that already. I was just listing a few devices that weren’t mentioned in other comments yet.
