[Elecraft] KIO2 Programmer's reference question

[Michael Studer]

I am trying to add new DSP filter features to my K2 control software, Marote, 
on Linux.  I just added the new DSP module to my K2 #1974.  So I had to play 
with it more.

I cannot get SW80 and SW81 to do anything.
I want to turn on the DSP NR mode.  
I am able to cycle through the various DSP filters using SW29.  And I can read 
the "audio filter" state via FW response string.  Of course it only tells 
what audio filter number you are using.  I see that there is a compromise 
here since the are 2 audio filter boards that could be installed in the rig.  
The plain old audio filter and the DSP module.  

Currently I am playing with adding giant usb tuning knob support to my 
program.  Maybe some of the Windows programmers may want to take a look at 
this thing.  Here is the link.
