If you if you can toggle off all DSP processing entirely, the answer
is yes. What you cannot do is install both analog and digital audio
filtering in the same K2.

Chris:
As you can see from other posts, opinions about the DSP module vary.
I have it and am very happy with it. I find the DSP narrow-band
filtering to be superior to an outboard QF-1 analog filter, and very
effective in enhancing the K2's crystal IF filtering. Set to the

I've been using a K2/KPA100 for about a year. The fan is audible, but
not distracting.
My specific recommendation is simply to use the rig as originally
configured by Elecraft.
