[Elecraft] KPA100 first test question

[Don Wilhelm]

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.
