I'm the packet hub BBS for the Dallas/Fort Worth area of Texas. This system forwards messages and bulletins in 4 ways:
In February 1994, I wrote an article for QST on how to DX with 2M packet. With the techniques that I used, I made contacts with over 100 countries via packet. I also presentated this information at various ham conferences. A copy of this presentation is available for download from my family web page.
