[Elecraft] K2 - REMOTE KPA100/KAT100

[Don Wilhelm]

Chris,
Installing the KPA100 and KAT100 together in an EC2 enclosure is really 
easy.  Order the KAT100-2 and you will have all the components needed to 
connect the KPA100 into the KAT100 board.  You will need a cable to 
connect from the KIO2 to the KPA100 (or the KAT100) DE9 AUX I/O 
connections - the materials needed are provided with the KAT100 kit.  In 
addition, you will need a short piece of coax with BNCs to connect from 
the K2 antenna output to the KAT100 AUX RF input.  Another short piece 
of coax with PL259s is needed to connect from the KPA100 RF output to 
the KAT100 ANT IN.  If you already have the KAT2 installed in your K2, 
it can stay - when the K2 determines the KPA100 is connected it bypasses 
the KAT2 and provides RF on the KAT2 ANT1 connector.

This is not a kludge at all - it goes together nicely and is almost 
'plug and play'.  If you do not have the KIO2 in your K2, add it, 
although there are a few solutions that substitute for the KIO2.  You 
will not be able to use the computer connection capability of the KPA100 
when it is mounted remotely, so if you want computer control, you must 
have the real KIO2.
