[Elecraft] KX3 receive discontinuity at 6.000 MHz

[Walter Underwood]

I was tuning in Radio Havana Cuba with my KX3 a few nights ago. I received them fine at 5999.999 kHz, but their signal and the background noise dropped way, way down when I tuned 6000.000 kHz. This happened with AM, USB, and LSB. It was also visible on my PX3. I bypassed the ATU, no change. Set the XPA100 to “not installed”, no change. Bypassed the ATU.X, no change.

KX3 serial number 2985, latest firmware.

Any clues? I’m tempted to do an EEINIT and reload the config, just on general principles.
