[Elecraft] K2: KAF2 Versus 2.2 kHz KSB2

[Linden, Mike (BRC-Hes)]

  I plan on building my KSB2 to KI6WX's 2.2 kHz crystal filter bandwidth
specifications (which is now the current Elecraft bandwidth). Should I shift
the KAF2's low-pass filter roll-off higher in frequency when I build it to
account for the increased bandwidth of the KSB2, or will the low-pass
roll-off be adequate as is?

  Thanks, Michael N9BDF
