There is an auto-mode for opposite sideband nulling to calibrate the KXFL3. I’d have to look at the manual to remember the specific keypresses for this, but it does show progress in the display (phase and gain) while running through the procedure. It is described in this document: https://ftp.elecraft.com/KX3/Mod%20Notes%20Alerts/RX%20sideband%20null%20A8.pdf.
Could that be what you put the radio into without knowing it?
