My first K2 serial 6613

This week I posted a question on the Elecraft reflector "I'm building a bare bones Elecraft K2 radio and later will be putting it up for sale what kind of options would a buyer be looking for?" I had received many replies and all were very good but also got me thinking. I had always thought of the K2 as a CW radio (selfish me as I am a CW op) but one of the first suggestions was to make the radio both CW and SSB friendly by adding the SSB option. To me that should had a been a no brainier as that opens the market much wider to more potential buyers. I was then also reminded of the invaluable add on that I put in my K2 radio (which is still in my shack and goes out on park and car expeditions) the rework eliminators by unpcbs. These folks have
developed a kit that allows the K2 to be setup and ready for any add on you want to put in the K2. Let me clear the waters a bit......if you build a bare bones K2 with no options but later you want to add some options,  it my require you to  remove some components from the K2 in order to add the option.

With the unpcb kit  there is no de-soldering on the K2. In a nut shell you unplug the unpcb board and plug in the K2 option. There is another great advantage to this, if you think you have a defective DSP filter (or any other option) board you simply unplug the DSP filter and plug in the unpcb board and see if the problem is fixed. Its time for me get off my soapbox for the unpcbs folks.......but if you ever are thinking about an Elecraft K2 build this add-on is well than worth the money!!! I just have to jump on the soap box  for a short time again.....On the top of the noise blanker rework board you see some resistors. These resistor (or other components) would normally be on the K2 board and have to be de-soldered to instal the NB board option from Elecraft. With the rework board you unplug the rework board and plug in the NB board. If there ever is a problem with the noise blanker (or any other option the rework kit looks after) you unplug it and plug in the rework board. You K2 will now work but without the NB option. Without the rework board you would have to re-solder in the components you removed for the rig to function properly.

From the post I received great suggestions on options that should be added while building the kit. The one idea I am leaning toward is to just leave the radio "option free" and

when the kit is done ask potential buyers what they want in the rig. So it becomes a radio that is "made to order" The buyer will pay for the options they want and a small fee for assembly, setup and installation but in the end they will have a radio that is customized to their radio needs. It's the way I have always wanted a car purchase to be!! At this point the kit is going through the parts inventory.
