[Elecraft] KAF2 or KDSP2 for K2 #5287

[Mike Harris]

G'day folks,

<snipo>
Let's widen the question to make it KAF2 or KDSP2 or NOTHING?  Does the
basic K2's crystal filtering work well enough that you (any of you)
would be happy with no AF filtering or does the AF/DSP filtering add
enough that you wouldn't want to be without it?

Unless there has been a circuit change in the stock K2 AF chain, the KAF2 
has the advantage of introducing a fixed low-pass filter which really 
cleans up the hf hiss in the audio.  It made listening to SSB a much nicer 
experience.  Given the choice of just a KAF2 or nothing I would take the 
KAF2 every time if only for this.

I believe someone mentioned that the KDSP2 tracks the crystal filter, it 
doesn't, and it always defaults to the first (af) filter settings on power 
up.

I could live without the KDSP2 but in its absence not the KAF2 for reasons 
mentioned above, I have both.

On another subject, what has happened to the Logger32 site, the domain has 
been out of action for weeks.

Regards,
