[Elecraft] KPA100/KAT100 EC2 Combo to ICOM 705

[Don Wilhelm]

Robin,

That will not work.  The KPA100 depends on internal signals from the 
base K2 such as AUXBUS and several other signals to operate and control 
power output.  In other words, it is an amplifier dedicated to the K2 
and not a general purpose amplifier.

The KXPA100 and KXAT100 would serve you better than cobbling up an 
interface that would be quite complex.

he signals needed are those in the 9 pin AUX IO connector.  AUXBUS 
allows the base K2 firmware to 'talk' to the KPA100 firmware IC as well 
as the KAT100 firmware.
