[Elecraft] KX1 ATU is resetting from TUN to CAL by itself

[Michael Madden]

Just a follow-up to my previous post...  It does not
always reset from TUN to CAL.  I have seen it reset
from TUN to other ATU settings like G03 or some other
random fixed ATU state.  

When I use only the internal AA's, I don't see this
problem happening.  Only on external 12V from 10
NiMH's.  

But I don't want to have to give up those nice 3dB I
get from the 12V and 4W vs. 2W!

Thanks,
