New blog post: Tianwen-1 safe mode telemetry. Peter from @amsatdl noticed that a few days ago Tianwen-1 was transmitting in safe mode. Here I analyze the telemetry signal, which is only 32 baud (16 bits per second). https://destevez.net/2026/08/tianwen-1-safe-mode-telemetry/

@Adam_AS_2 Hi Adam, for a quick technical reference would it be useful if future posts included a downloadable concise Fact Sheet? For example: https://disk.yandex.com/i/x_PMyBgMBezS4Q

@Adam_AS_2 Thank you! However, there is an oversight in my post, as I refer to 'CW MORSE' when it is actually 'MORSE-FSK'. I will fix it as soon as possible 😄
