I think that U1 was also defective..... because, even with the SSB
board removed, the K2 was always in TX when powered on.
I will order U1.... sniff...

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.

I found last week, with help from a few guys, that my problem was
the controller on the control board that was defective. I received
the one yesterday..... plugged it and turn ON the K2..... now I am
able the enter menu... the K2 in RX.... finally. But when I added
my SSB board, I found that the problem come again..... only when
the SSB board is inserted.
I found that when U1 is there..... pin 6 is short to ground... but
when I remove U1, pin 6 is OK.....
Is it possible that U1 on the SSB board is defective too !?!?!?!?
