RE: [amsat-bb] 100BaseT Woes

["Christensen, Eric" <CHRISTENSENE@xxxxxxxxxxxx>]

Are you using cat 5 cable?  It should be shielded.  You might try a
different length of cable...  Maybe the cable you are using is a perfect
antenna...  I've never tried iron ferrite coils for networks but that may be
an option as well...  Hmmm...

I hope someone has found an answer to this because this is driving me nuts.

I have a LinkSys BEFSR41 100BaseT Router, and it's totally whiping out 
145.800 (The ISS downlink frequency) at about 60 over S9.  I know it's the 
router and cabling because if I disconnect the twisted pair cabling into 
the shack everything drops down to about S2 (the rest probably coming from 
the router and the cable the server, both in the garage.

Is there any way to keep this stuff out of my shack short of running into 
the garage and cutting power to the router when the ISS comes 
around?  Seems extreme to do that.  I'm thinking maybe there are shielded 
cables or filters that can be added?  Perhaps I need to add a grounding lug 
to the router and ground it directly to the same ground as my rig?  I'm 
willing to swap out the router too if I can be sure that will solve the 
problem.

73,

Emily
