[Elecraft] K3EXREF

[Jim Sheldon]

David,
The exact conditions the anomaly occurs under are:  Tech mode ON, external reference 10 MHz signal connected and operating, go to MENU CONFIG, REF CAL (only available with tech mode on) and watch for the blinking asterisk.  If it is NOT blinking, the problem won't appear.  While the asterisk is blinking, use the VFO B control and go to any other menu item that has at least 4 letters in the VFO B portion of the display.  The 4th one will blink (same display position that the asterisk was in) and continue to do so in any other menu item that has at least 4 letters displayed in the VFO B window (only that window).  Once you exit the MENU CONFIG mode, the blinking will stop and not re-occur until you again display REF CAL long enough to see the blinking asterisk.

It does not affect the performance, only the display as far as I can determine.
