[Elecraft] K2 Options

[Dauer, Edward]

Still exploring options for a backup rig for the K3.   (The KX3 stays at the other QTH.)   Began looking into the K2.  The build sounds interesting.  One choice that has to be made is between the KDSP2 DSP filter and the KAF2 audio filter and clock.  Apparently it has to be one or the other - not both.  Any advice about that choice?  Anyone who chose one now wish they had done the other?  In case it matters I plan to operate CW only, and would probably go for the internal KPA100 and the external KAT100.  Thanks for whatever counsel might be offered . . .
