K3 Utility Version 1.2.10.27 is now available on the Elecraft web site at

This version contains the following changes:

 

-          Support for K3 Macros, introduced in Beta MCU firmware version
3.52.

-          Moved Calibration items to a new Calibration tab page.

-          Corrected a bug in multi-file firmware load; wait an appropriate
time for MCU reset to complete before loading the next firmware file.

I downloaded 3.63 and installed it.  Following a seemingly successful
installation, pressing the "ANT" button to change antennas generates an
error message:

   "No ATU"

"ATU TUNE" gives the same message.

I reverted to a Feb 14, 2009 saved configuration and ATU functionality
was restored.

Any ideas why this might happen?

Thanks es 73,

Go to CONFIG:KAT3 and be sure it is on.  If it says "not inst" then it
may have somehow gotten switched off.

Thanks, Kyle. It is set to "Auto".  But this was after reloading the
stored, older configuration.  So perhaps it was reset to "Not inst"
after loading the new firmware, but why would loading the new firmware
cause such a change?

I can't explain why it might happen, but on occasion after a firmware
load, especially one that is moving up several generations, it is
possible a config parameter might be altered.

I suspect if you reloaded the new firmware, and experienced the same
unexpected status of the ATU, it could be remedied through the CONFIG menu.

Also, after a major upgrade, and once you see all is working properly, I
recommend doing a configuration save using K3 Utility.
