[Elecraft] Malfunction of the Keys at the K3 Front Panel after Firmware update

[Don Wilhelm]

Chris,

Do you have a saved configuration file from when it worked right?
If so, you can do a "Parameter Initialization" as described on page 66 
of the manual, then Restore the configuration

Even without a saved configuration, you can try doing a "Save 
Configuration" now so you can restore it after the initialization.

If neither is workable, then write down the menu settings so you can 
restore them manually.

Should all that fail, Elecraft may have to original factory 
configuration file.  Ask by emailing support at elecraft.com with the 
serial number and original owner's name and callsign.

73,
Don W3FPR
