[Elecraft] K2: Extending AUX cable length

[KG3VTomZ at gmail.com]

Has anyone tried REALLY extending the cable between the K2 and the KAT-2? I  
would like to separate mine by 20 or 30 feet. What I want to do is get the  
KAT-2 and all the antenna conectors off of my oprating table, and close to  
the exit point of the shack.

I have heard the main concerns are noise (pickup and radiation) and timing.  
It would seem that using optical converters and optical cable might take  
care of both.

Any thoughts??
