[Elecraft] Using DSP with the K2

[robert parker]

I sometimes use an MFJ-784B DSP unit with my K2. It is used only when
Conditions are very poor and only with SSB.  No need for it ever in CW.

The DSP does work well but sometimes on the bands nothing works and even
those multi kilobuck transceivers fail.  

Generally there is no need for DSP with the K2.  The low noise floor and
great user programmable filtering works very well. Also I think the
audio filter (KAF2) is a must and will suppress much of the noise in
addition to the filtering. 

DSP will leave behind artifacts in the audio stream which can become
fatiguing to listen to.  It's almost as bad as the noise it was used to
suppress in some cases.
