Bob,
Do you hear sidetone on that K2 when in CW mode and hold the SPOT button?
If not, you have the wrong sidetone source selected.
Go to the menu for STL and hold EDIT to edit the parameter (if you do
not hear sidetone at this point, it is a sure sign that you have the
wrong source)
Now tap the DISPLAY button until you hear sidetone - exit the menu by
tapping the menu button twice.
If you can hear sidetone *and* you have a K2 with a SN under 3000, check
the wiring between CB U6 pin 25 and pin 1 of P4 to see if that added
wire is still intact.
73,
