[Elecraft] K2 Assembly Question

[Don Wilhelm]

DW,

Check the 8 volt regulator output (ControlBoard U4 upper leg).  If that 
is less than 7.6 volts, you may want to replace the regulator.  It may 
help with both problems.  BUT if your 8 volt regulator output is OK, 
then you should look for the component(s) that have the wrong value.
