There are two upgrade issues to consider:
(1) The recommended modifications to bring your K3 up to the
latest engineering level. Check
<http://www.elecraft.com/K3/k3_app_notes.htm> for what you may
need and how to install it.
(2) The upgrades to install the new K3S upgrade boards. The big
win here is the KSYN3A board. It will improve your receive and
fast CW break in. The KXV3B board adds a second preamp for 12,
10, and 6 meters. The KIO3B 3-board set installs an internal
"sound card" in the K3 for computer interface of digital modes.
It also replaces the RS-232 connection with a USB connection.
It is quite easy to install all three upgrade in a K3. Doing
them one at a time will be less confusing, but if you have a
good idea of how things in the K3 are connected together it is
possible to install them all at once. I, and my K3 survived the experience.

I've purchased a used K3 S/N in the 3ks, and plan to apply some of the K3S
upgrade options.
Any experiences, hints or do's and don'ts to tell for me?
I'm using the K3 mainly for HF contesting, VHF with an external transverter and
some DX chasing.
