[Elecraft] K2 - No Menu

[Don Wilhelm]

Ed,

Is this an older K2, or has it not been used in some time?  If so, it is 
probably the pushbutton.
The MENU button normally does not get a lot of use, so it is one of the 
ones that show a problem.
It can often be restored by tapping the button many many times, although 
replacing the pushbutton may be quicker and easier.  The wiping action 
of the switch contacts will remove any oxidation that has formed.

If you do replace the pushbutton, you will find the leads are difficult 
to unsolder - I even have trouble removing them intact with my Hakko 
808.  Cut the leads close to the switch body with small flush cutters 
and remove the remaining leads one at a time.
Clean up with solder wick and if solder remains in the hole, push it out 
with a wooden toothpick.
If you saved the "Switch Spacing Tool" from your K2 build use it to 
space the switch body above the board.  You can substitute a narrow 
length of PC board material.

73,
