MultiPSK is a perfect example of this. Little thought has gone into its GUI, configuration tool, etc. Too much effort is required to navigate the software while downing headache pain relievers to bother with it.
Traduction anglaise. The RTTY mode is a traditional mode used by radio-amateurs like,. RTTY, and use two frequencies which are filtered, each one corresponding to a binary digit (1 or 0). These two frequencies, separated by a shift, modulate the RF when transmitted and the modulation is called Audio Frequency-Shift Keying (AFSK), otherwise the modulation can be done directly on the RF carrier and it is called Frequency-Shift Keying (FSK). In RTTY 50 bauds with a shift of 450 Hz (and secondarily in 100 bauds), it is possible to decode the SYNOP/SHIP HF transmissions (WX information).
This mode is included into the software, there is the description of this mode and its variants as well as the specifications coming from his software. For 45 to 100 bauds speeds, mapping (ITA 2 standard) between the RTTY Baudot codes and the received or transmitted letters, figures and signs, as considered in this program, is as follows: 3 - 'A' ou '-' 25 - 'B' ou '?' 14 - 'C' ou ':' 9 - 'D' ou '$' 1 - 'E' ou '3' 13 - 'F' ou '!'
26 - 'G' ou '@' 20 - 'H' ou '#' 6 - 'I' ou '8' 11 - 'J' ou. 15 - 'K' ou '(' 18 - 'L' ou ')' 28 - 'M' ou '.'
12 - 'N' ou ',' 24 - 'O' ou '9' 22 - 'P' ou '0' 23 - 'Q' ou '1' 10 - 'R' ou '4' 5 - 'S' ou ' 16 - 'T' ou '5' 7 - 'U' ou '7' 30 - 'V' ou '=' 19 - 'W' ou '2' 29 - 'X' ou '/' 21 - 'Y' ou '6' 17 - 'Z' ou '+' 4 - Espace 8 - Retour chariot 2 - Retour ligne 27 - Chiffres 31 - Lettres. The small letters keystroke at the editor are translated in capital letters. The 27 and 31 codes (shift to figures or to letters) are only managed by the program and are transparent to the user. The 2 code (LF) is ignored because redundant.
