[Elecraft] KX3 - ATU Disabled Problem

[VaibhaV Sharma]

I tried disabling the ATU completely and still get the TX error.

I suspect there is something worse on the list here. But I don't understand
how the radio can go in this state with stable power and without any
transmission in progress.

Needs more investigation I guess. If I can't figure out by this afternoon,
will call support.

Thanks,
