[Elecraft] K2 filter attenuation

[Don Brown]

Hi

Another way to check if you are on frequency (assuming your filters are s=
et up right) is to hold the CW REV button. The CW tone frequency should b=
e the same on each side when switched. If one side is high and the other =
side is low just adjust the VFO a little to make them the same. For some =
people it is easier to hear a difference in two frequencies than to hear =
the zero beat of the side-tone.

If you haven't zero-beat the weak sig correctly, it may be falling off th=
e
edge of the tighter filter. Always look at the simple solution first. Thr=
ow
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 th=
e
tighter filter. You may just need to QSY a hundred or two Hz to bring the=
m
up. My rig is aligned fine, but my ear isn't. When they disappear, they a=
re
usually nearby. Now, if I could just hear whether to go up or down, not t=

lose them<g>.

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