[Elecraft] KX3 - ATU Disabled Problem

[Don Wilhelm]

Since your saved configuration did not work, that configuration may have 
an error.
Doing an EEINIT without going through the entire calibration procedure 
is bound to produce multiple errors of unknown types.
If your KX3 is a factory built unit, Elecraft may be able to retrieve 
the factory configuration file for you.  Contact KX3support at elecraft.com 
to see if they can send you the file.

You can do *all* the calibration manually.  Follow the calibration 
procedures in the manual.
