There are birdies around 14030, 21030, the low end of 10M CW and 6M that 
come from wired Ethernet. We hear our own plus those of our neighbors. 
They're free-running, so we hear multiples. These are what I hear on CW; 
there are probably others. I avoid them by using WiFi. My only exposure 
is a very short cable between modem and router, which I choke seriously.
When I was still in Chicago and still using wire Ethernet, broadband 
noise from it wiped out 2M from NSRC repeater.
