[Elecraft] K2/100 LOCKUP THOUGHTS?

[Jim Wiley]

Could have been a cosmic ray zap.  This is not a joke.  Cosmic rays can 
pass through a memory chip, altering its contents, and thereby what 
functions are affected.  Happens in computers all the time.   Usually a 
power off-on cycle will clear the problem.  Unless it starts to appear 
with regularity, I could dismiss this as a random event, and not worry 
about it.
