[Elecraft] K3 turns it self on, won't turn off

[Ian Maude]

Remove the RS232 board and wash it with clean water and a light brush.  Make sure it is well dried out and replace.  I am 99% sure this will solve your problem.  Some boards had some fluid left on after manufacture and developed this fault, mine included.  Washing the board removes the film.  I have had no problems since.  Use just water of course, no detergents :)
