Hi Andy, I just did a Google search and found a plethora of links for the mode. I went on the link below and found it to be really a good info source, very interesting:
http://www.bigskyspaces.com/w7gj/jt44.htm It still discusses 6M and up but YIKES! A single beam and 100 - 400 watts, pointed to the horizon for EME? Times have indeed changed. The only HF info/activity is appearing in this forum's threads. I'm intrigued by the implications for sure.

The same protocol is used since the software is the same. One station calls on the "first minute" (00,02,04,06, etc) and the other on the second (01, 03, etc). There is a convention that the most western station calls first when their is a scheduled "QSO" but I do not always see that followed. If you listen , and hear a signal CQing, note their sequence (first or second minute) and set up the software to respond accordingly. If they are CQing the first minute, you will be second minute and thus would check the auto box and not have 1st TX box checked. Andy K3UK
