If you have a little experience, you shouldn't have trouble building the K2. And the support staff at Elecraft won't let you fail, either.

Even the KAT100-1 requires a cable/connection between it and the K2. You need the KIO2 (or the KPA100) installed in the K2 in order communicate with the KAT100. You should consider adding a KIO2 to your order before you build the KAT100.

(Now please keep in mind I know absolutely zip/nothing/NADA  about the K2 or radios,  but I am an Engineerd).  Do the folks who use their K2’s in the field require an internal tuner?

It can be handy, I'm sure. Especially when dealing with the more random / compromise antennas used in the field.

Sure.

>  What are your thoughts.  My last question please. What’s “73” and I thought “Q” was aerodynamic pressure as in MaxQ ?   

"73" is a friendly "word" between operators. It is generally translated "best regards."

Q does stand for aerodynamic pressure (where it is usually lower case "q"). In electronic parlance, Q (generally upper case) indicates the quality factor, generally for an inductor or capacitor, and is the ratio of the reactance to the resistance of the device.

Q can also be used as an abbreviation for QSO. In the early, early days of radio telegraphy, a number of procedural signals were defined starting with the letter Q. These were three letter combinations that could be used to help communicate radio concepts -- possibly between operators who had no common language between them. These Q-signals were adopted by radio amateurs, and have become synonyms with certain radio concepts. A QSO is a contact between stations.

As you work to get your license, you'll learn about 73, Q and other things as well.
