Jim,
The K3 manual downloaded tonight, on page 69 says ...
======================================================================================================================
ERR EE2
==============
External EEPROM read/write test failed
================
EEPROM may be defective (front panel). However, this message may also
appear if power is turned off/on too rapidly, or if the power supply
voltage “bounces” during turn-on due to inadequate regulation. If the
power supply is not at fault, try re-loading MCU firmware first; then
try initializing parameters (pg. 66).
========================================================================================================================
Hope this helps.
73, Ted, W2ZK

Tonight my K-3 failed after being on for about an hour when I was
away.It displays ERR EE2.When powered on again the same ERR EE2 is
displayed.Tapping any button on the radio brings up a different error
message, such as DS1, FPF LOAD PENDING, BP1, LPF, IO3, IF1, and on and
on.Firmware reload is not possible. I sent Elecraft a support message
and will call Monday, assuming I will have to ship it for repair.Has
anyone seen this type of failure?Jim W6YA
