Jim, 7047.5 is in the DATA sub band outside the united states. The merits of that band position selection for FT4 are perhaps still debatable, but it is most certainly not in the CW segment as far as the rest of the world is concerned.
If we are going into history, even the placement of 7076 for JT65 and subsequently 7074 for FT8 set off a chain of events that has made 40m band plan global reconciliation problematic ever since. I believe a lot of the issues can be traced to the FCC mode/licence grade divisions and their seeming lack of recognition that the rest of the world does not have access to 300 kHz of 40m. Looking back in the past however will not help us move forward in the future. Today, in my humble opinion, any change to the status quo now on 40m or any other HF band plan (and even 6m where a large amount of activity is internationally focused below 51 MHz at least), needs to be done with the vision of trying to once and for all establish a single global band plan as far as possible through IARU. I can tell you this is no easy task and will require some give and take by operators of all modes. Unfortunately today it seems that the #mefirst attitude of a growing number of people is likely going to doom global harmonisation to failure. We unfortunately today find ourselves in an increasingly intolerant world and global cooperation has all but disappeared. Regards, Grant Willis VK5GR / KR1F P.S. this is drifting off the core purpose of this list but is also influenced by the use of WSJT based modes and what is programmed into the software that drives them. Please forgive me for taking this opportunity to describe a broader vision for how this could be addressed. > On 9 Jun 2025, at 5:57 am, Jim Brown via wsjt-devel > <wsjt-devel@lists.sourceforge.net> wrote: > > Hi Brian, > > Every journey/task begins with a single step. > > It would begin with a study of watering holes (dial frequencies) on each > band, with two concentrations.
