[Elecraft] Problem with routers and K2?

[G3VVT at aol.com]

It may also be a good idea to try the K2 on a dummy load to see if there is  
any effect then. The entry point of the interference needs to be tracked down  
somehow to enable a cure to be made.
 
Another problem that must be getting closer with ever wider bandwidths  being 
employed on broadband, we are getting closer to the point where normal  
broadband from the telcos is using part of the lower HF bands. I would guess  when 
that happens there really will be trouble. I did have a chart that  laid out 
the frequency span of data systems that is somewhere in my effects  I shipped 
back to the UK. From memory 2Mb when used for low definition digital  video 
(VHS video compatible) occupies the frequencies up to about 1.1MHz and the  34Mb 
needed for a compressed full definition video system goes up to about  12MHz. 
See there are 8Mb broadband systems on the loose now.
 
I wonder what frequency span they need?
 
Perhaps a list member with more knowledge on the subject could  comment.
