[Elecraft] AF1: First Impressions

[Don Wilhelm]

  Robert,

The AF1 is an audio filter, not DSP based, so it is comparable to the 
KAF2.  The AF1 has the added advantage of a variable center frequency.  
Yes, the KAF2 also has a variable center frequency (with 2 pots), but it 
is not a "Front Panel" control, once it is set, it cannot be varied at will.

73,
Don W3FPR
