"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?"
>From my perspective that's like asking "What would you rather have a box end wrench, rachet wrench or your fingers?" There is a place for all of those tools. If you're an avid DXer and/or Contester, you might want all of those options, at times. The ability to handle signals under any number of extreme conditions would be the deciding factor (or perhaps how much money you want to spend on bells and whistles). DSP & AF may not be of any real advantage if you have, say 16 3 wavelength long beverages on 160M, or stacked 5 element yagis on 20. If you have a simple low dipole on 80M, either or would offer you easier copy, at times. There are times during CW contests I like to run my filters at 800 Hz or even 1.5kHz, because folks call off frequency. But, if I'm trying to pull a weak multiplier out in the middle of the low end of 20 during the ARRL DX Test, I probably will drop down to 200Hz plus and use the KAF. Could I live without the KAF or DSP> Sure, I could... But both serve a purpose depending on the specifics of your station and operating activities. IMHO, both the KAF and DSP offer the low band operator advantages when working weak signals that make them both welcome tools to have on hand.
