I'm assuming this is because the 2N2 audio chain is tailored specifically for CW, whereas the K2's has to allow for SSB also.<br /><br />Your suggestion of an outboard SCAF is a good one. Looks like another kit is in my immediate future.<br /><br />Does the experimentation aimed towards bettering our stations never end? I guess not!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-12559579.post-34691293731265344552011-11-19T09:04:45.757-05:002011-11-19T09:04:45.757-05:00Dave,

It suppresses some noise; but I don't get that "pop out of the starkness" feature that I think you and I are both looking for. The built in crystal filters do a much better job of isolating a signal.<br /><br />You might want to consider perhaps a NE QRP Club SCAF filter. I think it's a better value.<br /><br />Larry W2LJLarry W2LJhttps://www.blogger.com/profile/11511736425569962662noreply@blogger.comtag:blogger.com,1999:blog-12559579.post-31184774827445749412011-11-18T00:11:01.982-05:002011-11-18T00:11:01.982-05:00Larry - I notice that you have the KAF2 audio filt...Larry - I notice that you have the KAF2 audio filter installed on your K2. I'm thinking of getting it for my K2 and was wondering how effective you think it is? I like tuning a CW signal that peaks noticeably within the passband of a receiver, and I'm also hoping that it will help to a certain extent with noisy bands.<br /><br />Anyway - just wondering what your impressions are of the KAF2.<br /><br />Dave<br />AA7EEAnonymousnoreply@blogger.com
