Description:

<p>WSJT-X met en œuvre les protocoles de communication pour radioamateur ou « modes » appelés FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65,
MSK144 et WSPR, ainsi qu’un mode appelé Echo pour détecter et mesurer son propre signal radio réfléchi par la lune. Ces modes ont été
conçus pour réaliser des QSO (contacts) fiables et confirmés dans des conditions de signal extrêmement faibles. JT4, JT9 et JT65 utilisent
une structure de message et un encodage de source (la compression efficace de messages standard utilisés pour des QSO minimaux) presque
identiques. Ils utilisent des séquences T/R 60 secondes synchronisées avec UTC. JT4 et JT65 ont été conçus pour des EME (réflexion sur
la lune) avec les bandes VHF/UHF/microonde. JT9 est optimisé pour les bandes LF, MF et HF. Il est à peu près plus sensible de 2 dB que
JT65 tout en utilisant moins de 10 % de la bande passante. Q65 propose des sous-modes avec une grande plage de durée de séquence T/R et
de décalage de tons. FT4 et FT8 fonctionne de manière similaire mais utilisent des cycles T/R de seulement 7,5 et 15 s respectivement.
MSK144 est conçu pour les trainées météoritiques (Meteor Scatter) avec les bandes VHF. Ces modes offrent de meilleurs formats de message
avec une prise en charge des indicatifs non standard et quelques compétitions populaires. FST4 et FST4W sont conçus particulièrement
pour les bandes LF et MF. Dans ces bandes, leurs sensibilités fondamentales sont meilleures que celles des autres modes WSJT-X avec les
mêmes durées de séquence, approchant les limites théoriques de leurs taux de débit d’informations. FST4 est optimisé pour les QSO bidirectionnels,
tandis que FST4W est pour des transmissions « quasi-beacon » (quasi-balise) de messages de style WSPR. FST4 et FST4W ne requiert pas de
synchronisation stricte et indépendante de l’heure et de verrouillage de phase de modes tels que EBNAUT. Le mode WSPR met en œuvre un
protocole conçu pour sonder des chemins de propagation potentielle avec des transmissions de faible puissance. WSPR est entièrement implémenté
dans WSJT-X, y compris des sauts de fréquence « band-hopping » programmables.</p>

en kaldt for Echo til at registrere og måle dine egne radiosignaler reflekteret fra månen. Disse tilstande blev alle designet for at lave
troværdige, bekræftede QSO'er under betingelser med et ekstremt svagt signal. JT4, JT9 og JT65 bruger næsten identiske beskedstruktur
og kildekodning. FT4 og FT8 er operationelt lignende men bruger T/R-cyklusser kun 7.5 og 15 s lange, respektivt. FST4 og FST4W er designet
specifikt for LF- og MF-båndene. WSPR-tilstanden implementerer en protokol designet til at teste potentiel propagationsstier i transmissioner
med lave strømforhold.</p>

<p>WSJT-X implementa protocolli di comunicazione o "modalità" chiamate FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144 e
WSPR, oltre ad una chiamata Echo per rilevare e misurare i propri segnali radio riflessi dalla Luna. Queste modalità sono state tutte
progettate per fare QSO affidabili e confermati in condizioni di segnale estremamente debole. JT4, JT9 e JT65 usano una struttura quasi
identica per la codifica del messaggio e della fonte (l'efficiente compressione dei messaggi standard usata per i QSO minimali).
Usano sequenze T/R sincronizzate con UTC e che durano 60 secondi. JT4 e JT65 sono state progettate per EME ("moonbounce") sulle
bande VHF/UHF/microonde. JT9 è ottimizzata per le bande MF e HF. È circa 2 dB più sensibile di JT65 mentre usa meno del 10% della larghezza
di banda. Q65 offre modalità secondarie con un'ampia gamma di lunghezze di sequenze T/R e di spaziature dei toni. FT4 e FT8 sono
simili dal punto di vista operativo, ma usano cicli T/R lunghi rispettivamente solo 7,5 e 15 secondi. MSK144 è progettata per il Meteor
Scatter sulle bande VHF. Tali modalità offrono formati di messaggio migliorati con la gestione di nominativi non standard e alcuni contest
popolari. FST4 e FST4W sono progettate specificamente per le bande LF e MF. Su tali bande le loro sensibilità fondamentali sono migliori
di qualsiasi altra modalità di WSJT-X con le stesse lunghezze di sequenza, avvicinandosi ai limiti teorici per i loro tassi di capacità
di trasferimento delle informazioni. FST4 è ottimizzata per QSO bidirezionali, mentre FST4W lo è per trasmissioni quasi-beacon di messaggi
in stile WSPR. FST4 e FST4W non richiedono la sincronizzazione temporale e di aggancio di fase rigorosa e indipendente delle modalità
come EbNaut. La modalità WSPR implementa un protocollo progettato per sondare percorsi di propagazione potenziali con trasmissioni a
bassa potenza. WSPR è implementata completamente dentro WSJT-X, inclusi "salti di banda" programmabili.</p>

<p>WSJT-X implements amateur radio communication protocols or "modes" called FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144,
and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. These modes were all
designed for making reliable, confirmed QSOs under extreme weak-signal conditions. JT4, JT9, and JT65 use nearly identical message structure
and source encoding (the efficient compression of standard messages used for minimal QSOs). They use timed 60-second T/R sequences synchronized
with UTC. JT4 and JT65 were designed for EME ("moonbounce") on the VHF/UHF/microwave bands. JT9 is optimized for the MF, and
HF bands. It is about 2 dB more sensitive than JT65 while using less than 10% of the bandwidth. Q65 offers submodes with a wide range
of T/R sequence lengths and tone spacings. FT4 and FT8 are operationally similar but use T/R cycles only 7.5 and 15 s long, respectively.
MSK144 is designed for Meteor Scatter on the VHF bands. These modes offer enhanced message formats with support for nonstandard callsigns
and some popular contests. FST4 and FST4W are designed particularly for the LF and MF bands. On these bands their fundamental sensitivities
are better than other WSJT-X modes with the same sequence lengths, approaching the theoretical limits for their rates of information throughput.
FST4 is optimized for two-way QSOs, while FST4W is for quasi-beacon transmissions of WSPR-style messages. FST4 and FST4W do not require
the strict, independent time synchronization and phase locking of modes like EbNaut. WSPR mode implements a protocol designed for probing
potential propagation paths with low-power transmissions. WSPR is fully implemented within WSJT-X, including programmable "band-hopping".</p>
