Randy, The KPA100 and KAT100 in an EC2 enclosure works FB. Order the KAT100-2 and the EC2 case. The KPA100 cables (except for the speaker) plug into the headers on the KAT100-2 board, so no change to the KPA100 are needed. The info by Lyle Johnson was for the KPA100 alone in the EC2, adding the KAT100-2 makes the task easier - just plug it in and connect a BNC cable from the K2 to the KAT100 AUX RF input.
You may want to change the 15 uH inductor on the KIO2 AUX2 board to a toroid - 12 to 14 turns on an FT23-43 or FT37-43 core will do, but the smaller core fits better. I have seen several of those small chokes go open when used with both the KPA100 and KAT100 mounted externally. 73, Don W3FPR Randy Moore wrote: > I'm considering adding the KPA100 and KAT100 to K2 #337, and building > them together in an EC2 enclosure so that I can leave my K2/10 in its > QRP state with the PA and ATU outboard.
