Hi
1.  I have lost sidetone.  I know there is a simple fix, but I can't remember it

2. Why when I remove the KDSP2  does the audio disappear ?

Thanks for your help

Brian,

Referring to the upper right corner of this diagram ...
http://www.unpcbs.com/common/images/diagram_large.png
the audio chain in a stock K2 is routed through jumper wires CTRL-R18 and R19.  
However, these jumpers are removed when CTRL-J1 and J2 are installed in 
preparation for the installation of the DSP.

You can use your K2 without the KDSP2 by jumpering from CTRL-J1-1 to CTRL-
J2-1 and from CTRL-J1-2 to CTRL-J2-2, i.e. from pin 1 on J2 to pin 1 on J2 and 
from pin 2 on J1 to pin 2 on J2.

Brain,

See W3FPR's previous post on this subject in the Reflector archives.  You 
can find it at http://marc.info/?l=elecraftm=117525815516404w=2


This topic is also described in section 8, Operation in the K2 manual 
under the section entitled Using the Menu.  (The exact page number will 
vary depending on the rev. of your manual.)

From page 86 in my rev. F manual ...

DISPLAY Switch Usage in EDIT Mode:  The DISPLAY switch is used to access 
supplemental parameters when editing certain menu entries.  You will 
normally not need to change these settings.  Entries which use DISPLAY 
include:

Entry  DISPLAY Switch Usage in EDIT mode
=  ==
S T L  Selects the sidetone source, U6-25 or U8-4.
   Use U8-4 (default).
