[Elecraft] KAF2 or KDSP2 for K2 #5287

[Tom Althoff]

Actually it might be more like saying "The MFJ antenna analyzer cannot be 
used in strong RF fields and other analyzers that I have used cannot be used 
in strong RF fields so I wouldn't recommend buying an antenna analyzer to 
check a Field Day dipole attached to the tower of a 50KW broadcast station."

I'm saying that ANY DSP radio Ten-Tec, Yaesu or Elecraft with RF or AF 
processing requires bandwidth to process the signal and throw away the 
noise.  Once you get a bandwidth under 200Hz the DSP code has little to work 
with to improve copy and can actually degrade the signal by adding 
artifacts.   Compare the KDSP2 to the KAF2 at 200Hz in a thunderstorm and 
then tell me which you prefer.

Since you did not say what mode you intend to operate nor what bandwith you 
prefer I could only state my experience from my operating conditions.

If you operated narrow bandwidth (under 200Hz) CW I suspect you would not 
feel the KDSP2 was worth the added expense.
