[Elecraft] Updated schmatics/errata question

[Bob Tellefsen]

Roland
Since your K2 is of a specific vintage, I recommend
you build it as it was designed at that time.  When
you have it working, you can always do the upgrade
kits, if you really feel you need to.
I'm still using serial number 12, without any upgrades
except firmware.  The firmware came with the options
I've added over time, like the ATU.  That is probably
the slickest option you will find for the K2.  It truly
makes it a portable, go anywhere radio.
Good luck and 73
