I know where you're coming from, Mike. Like you I built my own K2 from the ground up starting in 1999 and "completing" it in 2003 with the KDSP2 (and some other adds updates in 2014); I still use the K2 regularly even with a K3/P3/KPA500 etc. My favorite time in the hobby was building QRP rigs

Mike, I completely agree with your position. I suspect that Elecraft having not yet published a schematic is simply a matter of time. Schematics for most, if not all, of their products have been published, and the later ones (K3 and later) are on their website as pdf files. DX Engineering do

I was writing software for radios in 1981. Diagrams might help understanding, but the source code is the equivalent to a schematic. We already have a block diagram for the KX3 and people keep complaining. http://www.elecraft.com/manual/KX3%20Manual%20Block%20Diagram.pdf

Source code is too low level to get a conceptual understanding of what the software is doing -- a software architecture diagram is likely to be more useful for that. (in a similar way, for hardware a schematic diagram abstracts out implementation details such as PCB layout and track routing to m
