How do I identify *DOMINO* and *DominoEX* on the air? The signal sounds rather like MFSK16, a musical jumble of notes, but listening carefully, can be differentiated by ear. Several modes have a similar sound, but can be identified with care:
From http://www.qsl.net/zl1bpu/DOMINO/Index.htm - *DominoF* had an unusual "falling" sound to the tones, most obvious during idle, and sounded slower than MFSK16 - *DominoEX* has a very jumbled sound to the tones, no obvious idle, and usually sounds slower than MFSK16 - *MFSK16* has jumbled tones, but a distinctive low tuning tone to start, and settles musically to a low tone during idle - *Olivia* has very jumbled tones, much faster and wider, and a distinctive 'nee-naw-nee-naw' sound at the start of transmission - *ALE* is much faster and wider, and sounds like a turkey gobbling - it has only 8 tones *DominoEX* has no single idle tone, in fact idle cannot be recognised at all. It is hard to tell if *DominoEX* is received inverted, but the main data and secondary text won't print. The correct speed is always identifiable because the waterfall display will look sharp if correct, and blurred if incorrect. The default speed for *DominoEX* (11 baud) sounds slower than MFSK16, and is narrower (around 260Hz).
