Werner,
If you connect only the KPA100, the stock inductor is usually fine. If
you have aspirations to add the KAT100, or the Elecraft transverters,
then you should replace the stock inductor. About 12 turns of wire on a
small ferrite toroid core should work nicely.

I think you are referring to the part where he shows a circuit if you don't have
the KIO2 installed. There he says:
The inductors can be any small 15 uH nominal part, such as DigiKey M7827.
These are rated at 150 mA. The KAT100 only uses this for a very low
current, so it should be suitable for all three inductors. The KPA100 may
draw more current than this, so if you plan on using this cable for anything
other than a KAT100, you may want to consider a higher current rating on
inductor L1. I suggest at least 250 mA. You may wind such an inductor using
the directions given above.
Any comment on this from others who have the same setting with the
KPA100 in the EC2 enclosure? Do I really have to modify my KIO2?
