Description:
it: >-
<p>WSJT-X implementa protocolli di comunicazione o "modalità" chiamate FT4, FT8, JT4, JT9, JT65, QRA64, ISCAT,
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, JT65 e QRA64 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. JT65 e QRA64 sono state progettate per EME ("moonbounce") sulle bande VHF/UHF; JT65 si è anche dimostrato
popolare ed efficace per comunicazioni QRP mondali in HF. JT9 è ottimizzato per le bande LF, MF e HF. È circa 2 dB più
sensibile di JT65 mentre usa meno del 10% della larghezza di banda. Sia con JT9 sia con JT65, sono possibili QSO mondiali
con livelli di potenza di pochi watt e antenne approssimative. JT4 e QRA64 sono ottimizzate per EME sulle bande VHF e
superiori, e specialmente le bande delle microonde da 2,3 a 24 GHz.</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>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 FT4, FT8, JT4, JT9, JT65,
QRA64, ISCAT, 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, JT65 et QRA64 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. JT65 et QRA64 ont été conçus pour EME (réflexion sur la lune") avec les bandes VHF/UHF. JT65 s’est aussi
révélé populaire et efficace pour des communications QRP mondiales avec la HF. 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. Avec JT9
ou JT65, des QSO mondiaux sont possibles avec des niveaux de puissance de quelques watts et des antennes de compromis.
JT4 et QRA64 sont optimisés pour EME avec les bandes VHF et plus hautes, et particulièrement les bandes microondes de
2,3 à 24 GHz.</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>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>

were designed for EME ("moonbounce") on the VHF/UHF bands; JT65 has also proved popular and effective for worldwide
QRP communication at HF. JT9 is optimized for the LF, MF, and HF bands. It is about 2 dB more sensitive than JT65 while
using less than 10% of the bandwidth. With either JT9 or JT65, world-wide QSOs are possible with power levels of a few
watts and compromise antennas. JT4 and QRA64 are optimized for EME on the VHF and higher bands, and especially the microwave
bands from 2.3 to 24 GHz.</p>
