[Elecraft] Powering a k-pad from a K3S

Yes you have to modify the K3S. Check the archives, this was answered last
month by Wayne. I reposted a portion of his answer below:

You need to solder one end of an 1/8th-watt resistor to an SMD, and the
other 
end to a via nearby. Or you could send it to us to do the work.

Say, just for the sake of the argument, that I were to purchase a K-pad.  If
I want to power it from the K3S over the cable connected to the plug on the
bottom of the K3S, do I have to modify the K3S to get power to the K-pad?
If so, how much do I have to take apart?  Would it make any sense to
purchase any other stuff at this juncture because the K3S is going to be
apart, like the KDV3?  Thanks,  Bob    - W3DK
