[Elecraft] K2 - No CW Sidetone

[Tom McCulloch]

Hi,
  I seemed to have lost my CW sidetone (and the "spot" function as well) 
on my K2 - s/n 1103.  I'm getting audio from the receiver out of the 
speakers and the transmitter seems to be transmitting.

Any ideas?  is there a menu setting I may have accidentally turned off?

Tnx
tom
