[Elecraft] No K2 Sidetone

[Don Wilhelm]

Rick,

This comes up frequently, and thankfully was solved by firmware version 
2.04r.  Earlier versions had a toggle to change the sidetone source 
between U6-25 and U8-4 in support for older K2s without the wiring 
change for the sidetone source.

If your K2 is above SN 3000 or below that and has had either the KIO2 or 
KPA100 added, your sidetone source must be U8-4, and for those few K2s 
that do not fit that description, the source is U6-25.

Enter the menu for STL, edit the parameter and set the level to 
something reasonable (20 to 40 range), and then tap DISPLAY to toggle 
between the two sources.  Stop when you hear sidetone and exit the menu 
- problem solved.

73,
Don W3FPR
