[Elecraft] K2 is angry with me

[Don Wilhelm]

Colin,

The most common cause of the 'Loss Of Sidetone' problem is that you 
inadvertently changed the sidetone source in the menu.  If you tapped 
the DISPLAY button while adjusting the sidetone level, that would do the 
deed.
Bring up the ST L menu entry
Press EDIT to edit the parameter
Tap DISPLAY to toggle the sidetone source between U6-25 and U8-4  - you 
may have to tap DISPLAY a few times to get it right
When you hear sidetone stop tapping DISPLAY and tap MENU twice to exit 
the menu.

For your future operating convenience, do not change the sidetone level 
to match the signal when spotting - instead change the AF Gain to bring 
the desired signal to approximately the level you have the sidetone set 
to.  The sidetone level is not changed with the AF gain setting, so 
operating like that is possible.

73,
