Mandatory for the K2!  Time owned: 3 to 6 months
After building the Elecraft K2, I am very glad that I used the Rework Eliminator "un-modules" as part of the initial K2 build process.

I bought the *very* simple Rework Eliminator kit before I started to build the K2. The kit consists of a few very small PCBs with some headers, resistors and capacitors. It took me about 30 minutes to assemble this kit. The price of the rework eliminator PCBs is very low and their website includes a nice color-coded addendum, to the Elecraft manual, downloadable in pdf format.

Why is this un-module kit so nice? The excellent Elecraft K2 manual guides the purchaser how to build the basic K2 radio without any of the Elecraft options. This means not installing some parts and jumpering across some pads on the Elecraft PCBs.

That is not so bad, right?

Well when you decide that you want to upgrade your K2 with the Elecraft options, you have to disassemble the radio multiple times, unsolder jumpers and components on the Elecraft PCBs and then install additional components to make the K2 ready to accept the option that you purchased.

Some of the K2 disassembly steps and desoldering is not trivial. For example to add the K2's SSB transmit option, you have to remove the K2ís front panel, remove the front panel's PCB from the front panel Aluminum bezel (which requires removing all of the radios knobs which you have set so well with the Allen screws). Other options require the power transistor mounting screws and heat sink washers to be removed.

If you use the Rework Eliminator Option Bypass Headers, you can build the K2 one time and then not have to disassemble it to add the Elecraft options as you later build them. When you want to add an Elecraft option, you just assemble it, remove the Rework Eliminator bypass header that you plugged in on the initial K2 build, and install the newly built Elecraft option PCB!

I am very glad I did some research on the Web to learn about this kit before I started my K2 build.
