[Elecraft] K3 Spontaneous Failure

[Ted Roycraft]

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
