Description:

<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.</p>
<p>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 ottimizzato 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.</p>
<p>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.</p>
<p>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.</p>
<p>La modalità WSPR implementa un protocollo progettato per sondare percorsi di propagazione potenziali con trasmissioni
a bassa potenza. WSPR è implementato completamente dentro WSJT-X, inclusi "salti di banda" programmabili.</p>

<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.</p>
<p>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 synchronisée 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.</p>
<p>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.</p>
<p>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.</p>
<p>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 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.</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>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>
