The KAF2 actually starts rolling off about 1 kHz. This is nice for reducing the background hiss, but you do need to remove the KAF2 if you want to use Spectrogram to measure crystal filter frequency response. -John KI6WX ----- Original Message ----- From: "Linden, Mike (BRC-Hes)" <[EMAIL PROTECTED]> To: <elecraft@mailman.qth.net> Sent: Thursday, August 26, 2004 10:43 AM Subject: [Elecraft] K2: KAF2 Versus 2.2 kHz KSB2
