[Elecraft] KX3 Question

Sat Oct 13 23:47:47 EDT 2012

I want to qualify my previous posts on this topic.  I translated
information sent to me from Elecraft support to try to help.  What I wrote
was not explicit from Vic or Elecraft.  It was only my interpretation of
the communications I received in an attempt to help.
