[Elecraft] K2 DSP vs. Audio Filter

[Darwin, Keith]

Yea, me too!  I want those same answers :-)

I couldn't decide so I ordered the AF and have been using it for a week
or so.  Eventually I'll probably order the DSP and then try them head to
head, selling the one I don't want.

So far the AF is pretty cool.  I use the AF1 setting (wide AF bandwidth)
with wide and medium Xtal filter settings.  AF does a nice job of
eliminating wideband audio noise.  In the narrowest position (AF2) there
is some ringing but there is also more filtering.  I'm not sure yet
whether the AF2 is going to get used all that much.  It probably will.
On really weak stations the ringing doesn't help copy - I need more time
with it to really get used to it.

On SSB, I find the passive LPF in the AF did darken the response of the
rig.  I'm considering widening the bandwidth per elecraft instructions -
or maybe not.  I don't even have the SSB option in my rig, but I do
listen from time to time.

I am considering these two filters for a K2 that I'm about to buy. I'm
mainly a cw guy.
