I am using JTDX 2.1.0-rc148 and there is something I can't find an explanation for in the documentation. In the Band Activity window, next to the messages, I can see the country of the station who sent the message. So far so good. However, before the country name is either (1) no symbol (2) an empty circle (3) a filled circle (4) an asterisk Further, the country is sometimes in bold but most often not. What do these symbols / the bold vs not bold country name mean? On the right side, in the Rx frequency window, I also see mostly a tilde (~) between the frequency and the message. Sometimes I do see other symbols, such as the at-sign (@). Here, too, I can't find an explanation. Anyone having an idea what these mean?
