[Elecraft] K2 - KAF versus DSP

[Fred Maas]

The KAF2 has a very nice low pass filter in it.  It removes essentially all hiss, and just sounds nice.  I don't find the rest of the filter to be very effective.

The DSP is very effective, but lacks the hiss reducing low pass filter.  There is a solution to this.  Think about it.

I built the KAF2 low pass filter onto my DSP board.  Best of both worlds.
