[Elecraft] KX3 - Mode switch skips AM

[Keith Onishi]

Hello,

Tapping MODE switch on my KX3 with MCU 02.90, most latest firmware, switches mode from SSB -> CW -> FM, then back to SSB. It does skips AM.
I have not switched to AM for long time. I think I was able to select AM by tapping MODE before.
I went through KX3 Owner’s Manual to look for any configuration to skip any specific mode, but found none.
Sending “MD5;” from KX3 utility software switches KX3 to AM mode. So MPU is OK on selecting a mode except switching the mode by MODE switch.
I restored my KX3 configuration backed up almost 6 months ago, but the symptom is same. Then I reloaded the latest firmware to my KX3, but the same result.

Have anyone experienced the similar problem?
Your though on any possible cause are welcome.
