Short Description DominoEX, also known as just Domino, is an IFKIncremental Frequency Keying (Incremental Frequency Keying) mode developed by Murray Greenman ZL1BPU and Con Wassilieff ZL2AFP in 2004 that was the first fully developed iteration of the Domino IFKIncremental Frequency Keying family modes. Used to send text over RFRadio Frequency.

DominoEX, also known as just Domino, is an IFKIncremental Frequency Keying (Incremental Frequency Keying) mode developed by Murray Greenman ZL1BPU and Con Wassilieff ZL2AFP in 2004 that was the first fully developed iteration of the Domino IFKIncremental Frequency Keying family modes Used to send text over RFRadio Frequency. It is the successor to the developmental versions DominoF and DominoG.

IFKIncremental Frequency Keying (Incremental Frequency Keying) is used, where the data is represented not by the frequency of each tone, but by the frequency difference between one tone and the next. An additional technique, called Offset Incremental Keying (IFK+Offset Incremental Frequency Keying) is used to manage the tone sequence in order to counter inter-symbol interference caused by multipath reception. This gives the mode a great improvement in robustness.

DominoEX had optional FECForward Error Correction for all of it's available submodes.
