| FT8 mode od K1JT |
| 10 października wysłałem zapytanie do autora programu z powyższym problemem. Otrzymałem następującą odpowiedź ( bez tłumaczenia ): Are you familiar with FT8 and the other WSJT-X modes? Have you read the WSJT-X User Guide? Callsign details and restrictions in WSJT-X are fully described in the User Guide. For example, go here: http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-1.9.1.html#PROTOCOLS "An amateur callsign consists of a one- or two-character prefix, at least one of which must be a letter, followed by a digit and a suffix of one to three letters." SQ100S does not conform to this definition of a standard amateur callsign, as required for structured messages in the WSJT-X protocols. You can send "SQ100S" using the WSJT-X structured modes, but any message containing it will be treated as free text with maximum length 13 characters. QSOs using such messages are possible, but awkward. Part of the sensitivity advantages of FT8, JT4, JT9, JT65, QRA64, and MSk144 derives from the fact that standard callsigns are compressible as described in the User Guide. -- 73, Joe, K1JT |
