I happened to surf by SM3GSJ’s page a few days ago. Here I discovered that he has released a newer version of GcmWin. This is a great program for creating great circle maps of the world. You can also plot prefixes on the map, or create nice locator maps to keep track of your worked locators. Check out the program on http://hem.passagen.se/sm3gsj/
