[Elecraft] [K2] Curiosity about the kat module options

[Don Wilhelm]

  Pippo,

The KPA100 cannot cohabit the same enclosure as the KAT2 - they fit into 
the same space.

To do that, you would order the KAT100-2 and an EC2 enclosure.  Mount 
the KPA100 and KAT100 together in the external enclosure. The KAT100-2 
has connectors to plug the KPA100 cables (except for the speaker).   You 
will need the KIO2 option (or a suitable substitute) in the base K2.
You need a short coax with PL-259 connectors to jumper between the 
KPA100 ANT jack and the KAT100 ANT IN, plus a coax with BNC connectors 
between the KAT2 ANT1 jack and the AUX RF jack on the KAT100.  The cable 
to connect between the KIO2 and the KAT100 is exactly the same as the 
cable shown in the KAT100 manual.

When the K2 senses either the KPA100 or the KAT100 present, the KAT2 is 
forced to ANT1 and the L/C section is bypassed.

73,
