@justin I don't have experience but a few people that I speak regularly have. I believe it is not much diffent that the other digomodes (like with Fldigi). The only extra is that you have to have an exact time-source.

@justin I am much of a rag chewer, so I am not much into it, but propagation-wise on an empty band it can widen your horizon very much and let you work stations that are not workable otherwise.
