These modes have been reported in various places over the couple of years. Keep in mind that although a particular mode can be decoded, there are several that are encrypted, and therefore unreadable. One can use analysis tools such as ACF analysis to determine this, but we may never know what such signals are actually saying.
It should be noted that MARS, SHARES and numbers stations have sometimes used digital modes used in the Amateur Radio Service such as Olivia, MFSK16 or MT63. These modes are shown in bold, and will redirect to the Digital Amateur Radio article on this wiki to link to articles that describe the protocols in more detail.
