[Elecraft] PTT-Key Settings won't save

[Frank Stein]

Just clarify this strange behavior.
I use the Config Menu to set the PTT-Key to RTS-DTR.  As long as I don't
turn off the rig, it works correctly.  Once I turn off via the front panel
power switch, it loses this setting and goes back to OFF-OFF.
If while it is set to RTS-DTR I do a SAVE CONFIGURATION in the utility, I
can restore to the RTS-DTR values until I turn my power off.
Then it goes back to OFF-OFF.

Other config settings such a 1 or 2 speakers still can be changed and the
change is stored even after a power off/on.
Where are the settings stored in the K3?  EPROM?  Could one memory cell in
an EPROM go bad?
Is there a way to "factory reset" or something to clear this problem?

Thanks,
Frank
