When I installed my new synthesizer board in my Elecraft K3 I also wanted to take some pictures of the other boards that are in my radio. The reason for this is the K3 has many optional boards that can be added as the operator gets the funds or finds the need to add or upgrade a board. For this reason your rig can have a board with certain versions that go along with it. I have read on the Elecraft site for example a DSP board that is version "C" and above does not need a certain upgrade but the
Filters that are in the K3
boards below that can be improved with an upgrade. So this begs the question what board do I have??? I really don't want to tear down the K3 just to see the DSP board version. Another example for me is what darn filters did I instal in the K3?? I won't go on and I think you get the idea as to why I took pictures once the K3 was apart. Now having said all this I have on problem that I would like the input from my Elecraft readers. When purchased my K3 I ordered it with lots of options but since then I have lost the paper work detailing the options I ordered. Most if not all are very easy to see once you open up the rig.... but not the TCXO oscillator. I am not sure if I ordered the upgraded 1 PPM high stability or the stock unit? Below are 2 picture of what's in the rig now your input would be great!
