[Elecraft] Elecraft K2

[Don Wilhelm]

Matt,

The control cable should be constructed exactly like the one shown in 
the KAT100 manual.
The construction of the cable breaks out the pins used for the computer 
communications (2, 3, and 5) in the 'tail' which connects to the computer.
The other pins connect to the 'KAT100 tail' and contain the K2 control 
signals necessary to communicate with the KPA100 and KAT100.

The EC1 enclosure will not work - that enclosure is sized the same as 
the K1.
If you want to build the KAT100 into a smaller case, order the KAT100-1 
kit.  If you already have the KAT100-2, you can order the case 
components for the KAT100-1.
Elecraft does sell a kit to convert a KAT100-1 to a KAT100-2, but not 
the other way around.

So, if your desire is for a portable K2/100 plus KAT100, the smallest 
form factor is with the KPA100 mounted on the base K2 and a KAT100-1.
I think one would not build the KPA100 and KAT100-2 in an EC2 enclosure 
unless the desire is to retain the K2/10 for portable operation.

> So Don, that seems to imply that if you want to do CAT control of the K2 with an external EC2 enclosure, you need to make up a special cable that plugs in to the basic K2 K2IO connector and breaks out the computer control lines to one DB9 serial port connector, and runs the rest of the lines to the EC2 enclosure. Am I understanding this correctly?

Of course, this would mean leaving the KAT100 behind in the EC2 enclosure. Maybe the KAT100 could be put in a EC1 enclosure, so the home config is K2/10 + KPA100 in EC2 + KAT100 in EC1, and the portable QRO config is K2/100 + optional KAT100 in EC1.
