With all of Elecraft's radio kits the builder is able to purchase
add-on's to the radio either as needed, when able to afford them or if you want to expand into a new area of ham radio like FM or digital. At this point I am adding the KIO2 to my Elecraft K2, I want to remote mount the 100 watts amp (KPA100) and the antenna tuner (KAT100). To do so my next project is to build the KIO2 module. By adding this unit I am able to communicate with the K2 through my P.C. Also the K2 can operate along side the external amp and antenna tuner. So back to the KIO2 project.....the first step in the assembley is to mount two brass nuts to

the 9 pin D connector (DB9F). To make this part of the project go smoothly you begin by change the tip on your soldering iron. I have the
Weller WES51 soldering station it is a 50 watts unit and has been very reliable. I am able to change from a very slender tip to a larger tip for better heat transfer. I also add a little bit of solder paste to the nut and chassis of the DB9F. This helps the solder flow from part to part. Finally I have a larger diameter solder just for these types of jobs. This allows me to feed the solder to the spot were needed and I am able to get more flow of solder to that spot at one time. The next step seemed impossible to me at first, I was to press the small PC board between the top and bottom rows of the DB9F
