Hi Mike,
I agree with you. I sold my KDSP2 in return for a KAF2. The DSP functions in
KDSP2 are just primitive when compared with modern DSP rigs (e.g. K3).
I got my KAF2 in the second hand market at a much lower price. Of course, KAF2
is even more primitive but it is real cheap. You just pay the price for an
internal clock but with additional filter function.
I played around the KDSP2 with different settings (including the default one)
but the results were nothing encouraging. Yes, it did function as it was
advertised but the artifact was annoying. I am now happy with my KAF2 (just a
fraction of the price of KDSP2 in the second hand market).

主題： Re: [Elecraft] K2 noise
Hi Dick,
The KAF2 removes a lot of hf hash from the audio and makes listening
to SSB much nicer. An essential module I would say and many prefer
it over the more fancy and expensive KDSP2.
Regards,
Mike VP8NO
