Click Tune for digital modes is different. It uses the Click Tune
offset value to mode the signal to the ASFK offset value. For DIGL
(RTTY) that is 2210 Hz which is center between Mark and Space.
I can't access your jpg. I get a connection reset error.

Thanks for reply and information Tim.
I had that idea about the 50Hz for Tune Step.
On RTTY -as I show on the dump- would you click in the 'valley'
between the two mark and space signals ?.
I ask, because I think I have tested all possiblities without getting
the right method.

Click Tune is dependent on the Tune Step and mode. Depending how
close you click tune to the signal of interest, it will tune to the
strongest signal withing the frequency range of the Tune Step setting.
If you are tying to Click Tune SSB signals that are ~3K wide and the
Tune Step is only 50 Hz, you will probably not get Click Tune to
properly tune to the SSB signal's suppressed carrier frequency. SSB
signals need a Tune Step value of closer to 500 Hz to 1 KHz. I place
the yellow cross-hairs near the suppressed carrier part of the SSB
signal where the signal strength is the strongest to Click Tune SSB
signals.

Hi.
I'm a bit int doubt how to use click_tune.
A screenshot of how I see it is shown here:

Please tell me where to fire the yellow, to get it placed ok.
As can be viewed, the TuneStep is set to 50Hz.
