[Elecraft] Best way of running 100W?

[Don Wilhelm]

Stephen,

If you want to retain the QRP packaging at all times, you can mount the 
KPA100 in an EC2 enclosure.  It does require that you add the KIO2 to be 
base K2 in order to provide a path for the internal control signals the 
K2 uses to communicate with the KPA100.

If the KPA100 is mounted in the separate enclosure, the KAT2 is 
automatically bypassed (you must connect the KPA100 input to the ANT1 
jack) - but when you want to operate QRP portable, just remove the cable 
from the AUX I/O connector and the ANT1 jack and take the K2 with you 
leaving the KPA100 behind.

While separate mounting of the KPA100 alone is not an Elecraft approved 
mod, it is a fact that the KAT100-2 contains all the headers and 
connections necessary to mount that tuner along with the KPA100 in a 
separate EC2 enclosure.  The KIO2 is still need to provide the 
communications to the KAT100/KPA100 combination.
