> Does anyone run 100wpm ASCII RTY anymore? There is increasing use of 100 baud FSK SELCALL in ham radio. This is HF SELCALL CCIR 493-4 (Australian Selcall). HFLINK maintains a database listing of operators using it: http://tech.groups.yahoo.com/group/hflink/database
It is similar to Marine DSC (ITU-R 493-9) which is also 100baud FSK. It is only used with USB (upper sideband), and the mark (lower) frequency is fixed at 1700Hz. It uses FEC, and it is a very robust system. Bonnie KQ6XA
