[Elecraft] K2 Mods list

[Don Wilhelm]

  Rob.

You don't have that much to add to bring it up to level.
*E850138 - The temperature compensation for the PLL Reference Osc.
**K2KEYMDKT - The Keying Waveshape Mod (also requires updated firmware)
The Extremely Strong Signal Handling Mod - see application notes - no 
kit, but requires only 2 1N4148 diodes.*

That is all the official Elecraft mods to bring it up to the current 
level.  There are unofficial mods as well, but those are usually for a 
certain situation - choose wisely, if the intent meets your purposes, 
then try it, but if the originator's purpose does not fit you, then 
bypass it.  Examples of the latter are my K2 Fixed Audio Output mod and 
my CW PTT for the K2 (see my webpage www.w3fpr.com).
