About 7FSK, I said that I consider it not optimal, and, if decoded visually, I agree that it can be confusing and not adding much value. But the key stands in 'if decoded visually'. The greatest advantages of m-ary FSK and PSK can be obtained when the decision is done algorithmically, without subjective judgements. And, in addition, more robust coding schemes could be adopted. But, in spite of this, I see favourably the introduction of this mode, provided that some frequency discipline is adopted (an easy task), as it marks the rescission of the umbilical cord with CW, at least for weak-signal operations, where CW is not up to the task. For leisure QSOs, CW will reign for many, many years to come, I am sure. 73 es HNY Alberto I2PHD
