Of course, the next set of complaints will be "My filter display says 6 KHz, why is my AM audio response so narrow? On every other mode it shows me the high/low cut frequencies." > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of ERic - WA6HHQ > Sent: Thursday, March 27, 2008 1:57 PM > To: [email protected] > Subject: RE: re [Elecraft] bandwidth select on am mode re K3 > > > > We actually have -both- IF and AF DSP filtering in tandem in > the K3 for best performance.
