[Elecraft] Re: K2 Key clicks

Hello Earl,

I think there might be another way to do this.  If you can tune a K2 =
into
a fairly flat SSB filter, and center the tone in the band pass, say 1.5 =
kHz,
and feed that into spectrogram, you should be able to see clicks.

Of course, you have to do some fiddling around with settings - dots at =
30 wpm,
and enough dB range in spectrogram to show the skirts.  Also sampling =
rate,
number of samples, and so on may need to be fiddled.

Spectrogram provides a whole lot of very narrow CW filters all at the =
same time.

- And I like how Wayne is fixing it.

Like they always say: "Convolution in the time domain is equivalent to =
filtering
in the frequency domain."  - and you don't have to figure out what group =
delay
dispersion means :)
