[Elecraft] Splitting a K2/100 Using an EC2 Enclosure

[John Grebenkemper, KI6WX]

There is now a description on my web site that describes the detailed
modifications to move the KPA100 module from the K2 to a separate EC2
enclosure.  This allows you to run the KPA100 module remotely such as
installing it in the trunk of a car for mobile operation.  This type of
installation will even be more useful when the high power antenna tuner
becomes available later this year.

I do have one warning for anyone performing this type of modification to the
KPA100.  During testing of the KPA100 module, I found that extremely strong
spurious signals can be generated on 40 meters when several feet or more of
coaxial cable is connected to the KPA100 module RF input.  These spurious
outputs are not a problem when the KPA100 module is mounted inside the K2
enclosure as designed by Elecraft.  These spurious outputs may have
intensity of up to 1 watt of power and are not inside any amateur band.  The
instructions include a modification to the KPA100 circuit board to eliminate
this problem.
