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>

<p>WSJT-X implementerer kommunikationsprotokoller eller »modes« kaldt FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144 og WSPR,
samt 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>

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>
