I just ordered the new KXV3 RXA board for my K3. The instructions state requirements for the soldering station to be used in the installation of the
new board. My workshop has never had need for "high tech" soldering and consequently I do not own a soldering station. I have several assorted soldering irons and guns that have served me well in the past but I guess I will have to join the modern world. Since I would like to keep updating my K3 it looks like I will need to buy a soldering station. In looking through Googled references I see many stations in the $100 and up range. Is it absolutely necessary to spend that much to ensure the safety of my radio or are there some less expensive suitable alternatives? Nelson - K8DJC ------------------------------------------ That mod is one of the easiest in terms of soldering. You are soldering two fine wires to closely-spaced connector terminals that, if overheated, will melt the connector header or lift traces. But it's not nearly as critical as many component installations in other locations. Two more leads are connected to BNC connector terminals that require significant heat in any case. The RXA board comes with the leads pre-attached, so there's no soldering to do to the RXA board itself. It's a judgment call. Elecraft wants you to be successful and your chance of having trouble is greatly reduced by using the right tools, and a good soldering station is a tool you'll use again and again if you do any work on your rigs. You can get away with less. I've repaired a lot of SMD circuit boards sitting cross-legged on the deck in the navigating bridge of a ship using a portable butane-powered soldering iron while holding a flashlight in my teeth. I've also had lots and lots of practice over decades of soldering that lets me judge the temperature of the tip by the smell and, by being very, very careful, I've yet to destroy a board or parts. I did have the advantage of "growing up" with the pc board industry, first working on boards back in the 1960s that had large push-in pins to which leads were soldered, then boards with big thick, wide traces that have slowly evolved into the tissue-thin, tiny traces we find on many boards today. Even so, whenever possible I'll use a temperature-controlled soldering station in a comfortable, well-lit shop. Over time, I've found that a good soldering station costs me pennies a month to own and use. I don't consider that too much to spend to protect circuit boards, almost any one of which is worth more than the iron. I currently have a Hakko 936 that cost me less than $100 several years ago from www.tequipment.net. Bottom line, it's a matter of how skilled you are at soldering and how much risk you are comfortable taking with the pc board and components.
