The MMSSTV or YONIQ software has a log area on the right side. The "QRZ" field contains the other person's call sign. There are also default templates at the bottom of the software, such as S.templ 1, which includes templates 1, 3, and 5 for CQ diagrams, response to call reports, and 73 end-of-communication diagrams. I believe that using these three diagrams is sufficient to complete communication. Currently, I am mainly receiving messages, but it seems like no one has received the images I send 😢
