The modem code for dominoEX uses a wide band multiple frequency
detector that can lock on and detect the incoming signal even when
badly mistuned.  Frequency domain oversampling is used to allow
proper tone detection without the need for AFC.  The AFC control does
not alter the decoder in any way.
<br>


The waterfall and digiscope will appear as:
<br>

<br>

The text displayed in the status area is
the secondary text being sent by the transmitting station.  When
the keyboard buffer is empty the dominoEX modem transmits text from the
secondary text buffer.  Your secondary text buffer can be edited
on the DominoEX configuration tab.
<br>

The digiscope display represents the tone pairs moving through the tone
filters. You can also use an alternate digiscope display (left click on
the digiscope display area).

<br>

In this display mode the red line represents the center of the multiple
tone bins that are in the detector.  The dots will be blurry if the AFC is
not locked on and become very distinct when AFC lock has been achieved.  The
tone dots will move from bottom to top (opposite the direction of the
waterfall).

This is the same signal mistuned:<br>
