[CQ-Contest] Router Recommendation?

Hi Scott,

What kind of internet connection? DSL modems are notoriously poor at 
rejecting RF, and 160M is within the range of their data signal. Part of 
the problem is telco wiring around your home -- replacing it with high 
quality twisted pair data cable like CAT5/6 can help. But when their 
modem is the problem, the best solution is to call your provider and 
tell them to fix it. W8JI did that years ago.

Have you considered WiFi for networking? That significantly reduces RF 
related issues, including internet birdies on the ham bands. I started 
replacing wired Ethernet with WiFi when I lived in Chicago, and am doing 
the same here in NorCal.

As to ferrites -- it takes a LOT of turns through one or more #31 cores 
to make an effective choke for 160M. If you haven't already done so, 
study k9yc.com/RFI-Ham.pdf
