[Elecraft] K2/10 upgrade question

[Don Wilhelm]

Tom,

The answer is 'yes' or 'maybe'
You need a mechanism to carry the internal K2 signals needed by the 
KPA100, and the KIO2 provides those.  The KIO2 also provides 3 RS-232 
signals that can communicate with a computer.

There are substitutes for the KIO2 that will provide the internal K2 
signals to the KPA100, but do not provide the RS-232 capability.

The computer communication is not lost if you use the KIO2 - the cable 
required is the same as the one diagrammed in the KAT100 manual.  You 
will not have computer communications capability from the AUX I/O 
connecrtor on the external KPA100 - that is only available when the 
KPA100 is mounted on the base K2.  If you need computer connection to 
the K2 when mounting the KPA100 externally, then the KIO2 is required.

73,
