Thanks, David. I never loaded 4.57 and the current notes on the Elecraft K3 firmware page don't include this item. I'll have to be more careful to read all of the release notes for versions between that last loaded and a new one.
This would have been a more seamless upgrade if the firmware had been able to detect the K3EXREF module and "do the right thing"; that is, if the module is present, set the config menu item to enable it. Hard to imagine why I would install the module and then not use it. Perhaps the detection is not possible. David G4DMP wrote > Check the release notes, Stan.
