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.
We have pages set up with just waterfalls (useful for quick searches) here;
The PACTOR references are shown in bold will redirect to the HF Digital Amateur Radio article on this wiki to link to articles that describe the protocols in more detail. PACTOR1 through 3 have been known to be used in the amateur radio service, as well as in the maritime service, as noted. ALE has also been known to be used in the amateur service.
'Last Seen' references are the last time this mode was seen in the UDXF logs.

Sporadically Active Modes
These modes have been reported occasionally over several months. Some may have been just tests; whether they'll show up in the future is anyone's guess. Text is always encrypted and can't be read, though it can be decoded in many cases.

Amateur Related Modes Used by Other Entities
These modes have been reported once in a while by SHARES, MARS or the ICRC. Their use is sporadic at best.
MFSK32 and 64 is currently being used by the Shortwave Radiogram program. Olivia and MT63 has been used in the past. See the Shortwave Radiogram Gateway for more information on this subject.
