There is a discussion about Ethernet carriers going on on RFI list at Contesting. I am about to try using 10 mbit multimode fiber, which though slow, is fast enough for external links, which are the longest runs. Using shielded cat5 for the short runs of 100MBit Ethernet seems to help those, though some radiation occurs from the router and hub and switch boxes, and their infernal switching power supplies.

Good Morning Group,

I am back on the air (4991) after nearly 20 years.  The first thing I
noticed was all the interference on 20 meters.  Hetrodynes everywhere!
What's going on?

Took me a while to figure out that it was the computer - not there 20 years
ago!

So, other than removing it from the shack (ghastly thought) is there any
font of wisdom on this subject or general guidance?

Thanks and 73,

Tom, W3QS
