It's the Ethernet stuff related to the router. The cables are acting as
transmitting antennas, your ham antennas are receiving the noise. The
solution is multi-turn ferrite chokes on each of those cables. Five
turns on a #43 or #31 core will make a nice dent in the noise. See
http://audiosystemsgroup.com/RFI-Ham.pdf for details, and for part
numbers and vendors for suitable ferrite cores. EVERY cable can radiate
the noise, including the power cables, so every cable should be choked.
