[Elecraft] K2 v K3

[Geoffrey Mackenzie-Kennedy]

Don,

Perhaps you have suggested one possible solution to making the output from 
DSP sound less harsh ('yucky' is a better term IMHO), add some harmonics of 
the desired output signal. I can't at the moment see how this could be done 
with relatively simple circuitry which would have to distinguish between the 
desired output signal and any unwanted artifacts at the DSP's output, and 
not introduce any additional undesired artifacts. Just a thought not aimed 
at any particular radio which uses DSP.

73,
