FW: [Elecraft] K2 filter attenuation

[Dan Barker]

If you haven't zero-beat the weak sig correctly, it may be falling off the
edge of the tighter filter. Always look at the simple solution first. Throw
a Spectrogram on the output of the rig on a weak one, and see if the CW
spike (or bump, if it's really weak) is dead-denter in the passband on the
tighter filter. You may just need to QSY a hundred or two Hz to bring them
up. My rig is aligned fine, but my ear isn't. When they disappear, they are
usually nearby. Now, if I could just hear whether to go up or down, not to
lose them<g>.

No this is not normal for a properly aligned K2. <snip> [but perfectly
normal for a poorly aligned ear!]
