[ICOM] Wired vs Wireless Routers for RFI

[Dave Holford]

Hi John,

I installed a D-Link DI-604 wired router a while back, using Cat-5 cables.
The router is within 8 feet of multiple receivers, and router and cables 
are about 20 feet from the feedpoint of an inverted L.
I have not noticed any increase in noise or birdies over the stuff that 
was there before - neighbors TV and stuff!

Also there is no evidence of RF to the network on any frequency from 
160m to 70cm running 100 Watts on HF and 30-50 Watts on VHF/UHF.
