Is there any difference between the official modifications and this one:
http://ur5lam.jimdo.com/elecraft-k3-mod-s-page/ ? I find it a bit difficult
to see exactly what the unofficial mods are as it isn't entirely clear what
components / boards are affected from the photographs. I can't really
justify the cost of replacing the DSP board given that I don't think there
is much wrong with the K3 audio at the moment. But I have a big bag of
assorted electrolytic capacitors sitting in my junk box.
