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.

The waterfall and digiscope will appear as:

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.

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).

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).
