[Elecraft] still have a problem.... still TX on power on

Jean-Francios,

I am sorry to tell you that apparently your KSB2 U1 is likely to be damaged.
Is it possible that there was nothing wrong with Control Board U6, but 
the entire problem was KSB2 U1?  There is a possibility that both were 
bad - that happens, but rarely.

73,
