Dave,
There are no menu items - KEYOUT should "simply work".
Make certain it is not the cable - put your ohmmeter in the KEYOUT jack.
During receive it should show an open circuit.
During transmit is should be close to zero ohms.
If that is how it behaves, the K3 is working properly.
Unfortunately, there is an unpredictability with lightning strike damage.
Devices (ICs, transistors, etc) may work when tested and then fail
shortly afterwards. That is something impossible to diagnose.

I have a K3s #10113 that was involved in a lightening strike and just returnedfrom
Elecraft after repair and upgrades. My KIO3B was destroyed "beyondeconomic
repair" and a trace was burned and repaired on the RF board. Ihad the general
coverage module add as well as the 8 - 10W 2 meter xvtr.
All looked and functioned well until I attached an amp. I have a couple of
ampsboth had worked well with this K3s prior to lightening and were not
involved inthe lightening incident.
When I connect the amp from the K3s "KEY OUT" jack to the "RELAY JACK" on
inthis case an Ameritron AL80A the red TX lamp on the K3s comes on.
I've looked through everything in the manual looking for a menu item that I
mighthave wrong but can't find a thing. Additionally I called a friend who has
owned ahalf dozen or more K3 and K3s transceivers and he has never seen this.
I'm not very technical, but at age 75 had little trouble assembling the K3s
from kit.
I would hate to have to send my beloved K3s back to Elecraft again,
especiallyat $100 shipping round trip!
