[Elecraft] K2 Menu Button

[Michael Carter]

Hi Aaron,

The symptoms you describe indicate to me a mechanical
flexure problem.  I would pull the Front Panel board out
of the RF board socket (first removing the Control board)
and carefully inspect all pins for corrosion.  I would also
inspect the solder joints on the Menu/Edit button switch.

The failure of the Menu/Edit button switch to produce any
response on some occasions while causing display blanking
and loss of receive function on others is odd, but the fact
that cycling the Power switch restores function suggests
that mechanical forcing on the RF board is sufficient to
reconnect an intermittent power feed to the Control and
Front Panel boards.  I'm betting the J1/P1 connector junction
between the Front Panel board and the RF board
is the source of this behavior.
