[Elecraft] K3 serial cable

[Paul at N4LCD.com]

So the K3 F/F DE-9 serial cable only needs TX, RX, and SG?

Pins 2, 3, and 5 only...

Straight through...

I've got some cable with one twisted pair inside a foil shield with 
an un-insulated ground wire (I believe it's called the drain) in 
there too, and it contacts the foil shield full length.  Would that work?

Should I slip some ferrites (which I already have) over the cable's 
jacket before soldering the DE-9/F's on?
