I did a search on Q15X25 and revisited the yahoogroup. And I now recall that I asked some of the same questions a number of years ago when this was first being tested because I was on that group for a short time, but by then things had not gone well.
A number of people who were on that group are on this group as well and their silence tells you that it is just not going anywhere at this point. This was also the general viewpoint on the discussion group, but curiously, while some found that it was very ineffective, there were those who gave me the impression that it was much better than 2FSK300 packet. Since the mode is not adaptable, and always quite wide, this limits its weak signal capabilities, but the tones, spacing, and baud rates seem to be very reasonable. In fact, isn't it fair to say that it is very similar to Pactor 3 at its higher Speed Levels, but running at DBPSK instead of DQPSK and a slightly slower baud rate, but almost the same tone spacing? 73, Rick, KV9U maiko4 wrote: > Rick, > > >> I am set up with Q15X25 tonight.
