[Elecraft] [K3] Auto Shift/Width - Possible?

[Don Wilhelm]

Pete,

I believe the Auto-Spot feature is the closest thing to what you are 
looking for.
If you need to get more sophisticated than that, I would suggest you 
connect the K3 to the soundcard input and use something like Spectrogram 
or some other FFT based audio spectrum analyzer to give you a view of 
the receive passband and the signals in it.

Normally, you should center the filter passband at your CW sidetone 
(spot) frequency, and use the VFO to move the signal to that frequency.  
Once you get close, auto-spot will move it 'right-on'.

A bit of practice with Spectrogram (or other) could give you a better 
feel for the effects of the width and shift controls.  You can download 
version 5 of Spectrogram from Tom Hammond's website www.n0ss.net.  Tom 
has some setup information on his site as well.  Try it and see if that 
helps.  If nothing else, it will give you some practice "training your 
brain" to recognize tones a little better.

73,
