[Elecraft] K2 Upgrade

[Jim Wiley]

Ron -


You may want to consider mounting the KPA-100 and the KAT-100 ATU in a 
separate EC-2 enclosure.  That allows you to keep the basic K2 "as is" 
for portable use, while still retaining the 100-watt capability for home 
use.  I have taken this route, and it works well (for me).  There is 
some additional cost, but not all that much, and the added versatility 
is quite useful.  You will need to obtain a KIO-2 interface module  for 
the K2 if you  don't already have one, and build a cable to connect the 
serial data.  .  This is needed to route the control signals to and from 
the 2 boxes. Also, one change I made while doing this was to leave the 
speaker in the base K2, and not install a speaker in the KPA-100, 
further simplifying things.  The assembly is easy, and no hurdles need 
to be jumped.  A tutorial, complete with pictures, is available.


Your mileage, of course, may vary.
