[Elecraft] Re： K2 noise

[Johnny Siu]

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).

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,
