[Elecraft] swapping in KAT2 in place of KPA2

[Don Wilhelm]

Alan,

Not much at all to do the swap.  Remove 6 screws holding the KPA100 - 2 
on the rear panel, one at the top center of each side panel, and 2 at 
the front of the KPA100 assembly.
Now you can lift the KPA100 away from the K2 - tilt it so it is upside 
down to the right of the K2.
Unplug 3 cables along the right side of the K2 RF Board (AUX RF, AUX DC, 
and speaker) also unplug the ribbon cable going to the Control
Board.
The KPA100 is now free.

To install the QRP cover with the KAT100, hold it upside down to the 
right of the K2 - plug in the coaxial cable to the AUX RF header, plug 
the speaker into RF Board J5 (not control board J5), and plug the 4 
conductor cable going to the KAT2 into the 10 pin header on the Control 
Board - be certain the green wire is at the top.
Rotate the QRP top cover in place over the K2 and use 6 screws to hold 
it (same locations as the ones removed for the KPA100).

That is all there is to the task - it can be accomplished in one to two 
minutes after you have done it once.

73,
