Thanks for the explanation. A few years ago, I expressed concern that hams were drifting towards the Internet and expensive PACTOR modems for emergency messages. Now with RMS Express/Winmor, PSKmail,and NBEMS , we have plenty of good HF options to choose from. The large network of RMS stations on HF has several advantages in North America, in Europe I think PSKMAIL has a wider network.
