[Elecraft] K2 upgrades?

[Don Wilhelm]

Johnny,

Since any builder can upgrade a K2 by installing the A to B Mod plus any 
other associated mod kits, you will have to determine the level by 
inspection.
Download the K2ATOB instructions and look at all the associated upgrade 
kits listed on the first page - then download the instructions for each 
of those upgrade kits.

Remove the top and bottom covers from your K2 and compare your physical 
board with the instructions for each upgrade kit.
Often owners have installed one or two upgrade kits from the full A to B 
upgrade, but have not done others.

A fully upgraded K2 can perform just like a newly built kit.  That fact 
makes it difficult to predict what upgrades are still needed other than 
inspection of the parts installed.
