======================================
I built the SCAF 1 and agree with one exception:  I don't have good
communication headphones and use Sony stereo 'phones.  These are hifi and I
get serious thumps from the K2, even with the AF 1 turned on.  This is true
with other rigs as well.  The SCAF 1 removes this noise.  I just need to
make sure I don't overdrive the SCAF 1 as it is very sensitive to this.  The
filter really cleans up less than pure sidetone audio, too.  I would like to
get some good communication 'phones, without the microphone thingee.  Any
recommendations.  I like the kind that seal out external noise.  I like to
use a bug but the damper clacking is distracting to me.
