[Elecraft] K3 - ERR BP1, XV3, AT3, IF1

[Jim Miller]

These are intermittent.  They appear at power on just before the welcome
message.   At first I thought it was only ERR BP1 but since I have realized
that pressing the disp button also shows the others if I can do it fast
enough to read them before they go away and into the welcome message.  They
are getting more often and mostly do not go away with power down and up
again.  Guess it is time to break it open.

 

I have also been have having occasional trouble with no power out.  This
only happens from power on and not during operation once going.

 

Just wondering which is the real problem.  The last thing that was done and
this is not "recent" is to remove my KIO3 bd and  install the KIO3A board so
I can connect my internal 2 meter module (not yet done).  I don't think I
had this problem before that.

 

Which of the listed errors is likely the "root" cause of all?
