[Elecraft] Sidetone source

[Don Wilhelm]

Bill,

The selectable sidetone source is for support of older K2s that have not had
the wiring change made for the new sidetone source.  It has been a source of
confusion many many times and IMHO should be eliminated in the next firmware
release (which would require those older K2s to apply the hardware change if
the firmware is upgraded).

Bottom line, your K2 (like all post-SN3000 K2s) has only the U8 pin 4
sidetone source built into it - and there is nothing missing.
