My terayon router for where the ISP enters my house is in my personal server rack, and it still generates noise. If I go to my basement radio desk by my server rack, I can forget about Apco25 digital on my XTS3k/5k, or the digital scanners. Just seperate the router from the radio.
I actually moved one of my repeaters from the basement to the attic because of so much crap from the router, and this was with heliax coax, too.
