[Elecraft] ] Elecraft] KPA500 to K3 control cable

[Steve Kercel]

Another trick that works:

If you're using a K3 and KPA500, there are only 9 lines needed, and two 
of those are grounds. A CAT5 cable has 8 lines. If you use one line for 
ground and connect it to both ground pins at each end, you have the 
necessary 7 lines left. I used this scheme to build a 15 foot jumper. It 
works perfectly. I discussed this with Eric before I tried it.
