[Elecraft] K2 question on options

[Geoffrey Mackenzie-Kennedy]

Ron,

I opted to include the KAF2 option when building my K2/100 rather than the 
DSP option, and have found that the KAF2 audio filter is a worthwhile 
addition to the receiver. FWIW I use a sidetone (beat note) between 350 and 
400 Hz when copying CW, and when there is a lot of "on frequency" QRM the 
KAF2 can help to dig out a weak DX SSB signal.

73,
