I have recently been researching methods for SSTV communication on shortwave, but I found that there was a lot I didn't understand and very little reference material available. However, I have made some progress recently, and now that I have time during the holidays, I have compiled an SSTV communication operation manual based on my experience using the XieGu G90 radio. The manual primarily covers the preparation of software and hardware for SSTV communication, as well as connection and configuration methods.

Sharing this for everyone's reference. Please check for any omissions or inaccuracies. This is BI1SFC, 73!
