[Elecraft] K3 DSP Old and New

[Don Wilhelm]

Doug,

I also have the older DSP board.  I elected to add the Low Pass Filter 
add-on-board because I was not interested in the extended low frequency 
response.
So the proper answer depends on your aspirations - the low pass filter 
does provide a definite advantage in high frequency 'hiss'.
