[Elecraft] DATA A Mode Changes to AFSK A

[list1]

Hi All,
I just noticed something that tends to happen on my K3.  I had problems
running MT63.  The finally found the problem and it was that the radio had
changed from DATA A digital mode to AFSK A mode.  Changing it back to DATA A
fixed the problem.  When I turned the radio off, waited 10 seconds, and then
turned the radio back on the radio was still set to DATA A.

However, I checked the mode this morning and it was back to AFSK A again.
The frequency had not been changed.

I don't know if it is me or the firmware.  (I am betting on the former)

Firmware is 2.78
