Nuovo modo digitale FT8 da K1JT

Eh si, il mondo della radio è sempre in evoluzione. 

Il noto radioamatore americano K1JT  ha rilasciato un nuovo modo di trasmissione digitale chiamato FT8, per ora integrato nel programma di codifica e decodifica WSJT-X in versione beta dalla release numero 1.8.0-rc1-

Come dice la pagina di WSJT-X, questo programma  implementa molti protocolli di comunicazione o “modi”:

JT4 , JT9 , JT65 , QRA64 , ISCAT , MSK144 e WSPR , così come quella denominata Echo per rilevare e misurare i propri segnali radio riflessi dalla Luna.

Queste modalità di trasmissione  sono stati progettati per rendere affidabile e  confermare  QSO con  segnali estremamente deboli.  Video dimostrativo

DroidRTTY is an application to decode and encode RTTY

DroidRTTY is an application to decode and encode Ham Radio RTTY with the build in microphone/speaker or wired to your radio.

A waterfall shows the frequency spectrum of 100Hz to 2500Hz. Just slide the waterfall slide on a RTTY carrier frequency and DroidRTTY will decode the signal.

In transmitting mode characters can be entered trough the keyboard. 9 Macros are also available to store standard texts like “name and qth” and “station info”

DroidRTTY also now includes a logbook. Callsign, Name RST etc can be easily tranfered into the lookbook from the receiving screen.
The logbook also includes ADIF export and import to transfer your logbook data to a PC based logging software.

 

DroidRTTY è un’applicazione per decodificare e codificare RTTY

Una cascata mostra lo spettro di frequenza di 100Hz a 2500Hz. Basta far scorrere il vetrino cascata su una frequenza portante RTTY e DroidRTTY decodifica il segnale.

Nel trasmettere in modalità caratteri possono essere inseriti attraverso la tastiera.  Le macro sono disponibili anche per memorizzare testi standard come “nome e QTH” e “info stazione”

DroidRTTY ora include anche un diario di bordo. Nominativo, nome ecc RST possono essere facilmente tranfered nel lookbook dalla schermata di ricezione.
Il registro comprende anche l’esportazione e l’importazione ADIF per trasferire i dati del giornale di un software per PC di registrazione.

DroidPSK is an application to decode and encode Ham Radio BPSK31

DroidPSK is an application to decode and encode Ham Radio BPSK31. A great tool for portable Amateur Radio PSK operation.
DroidPSK is able to decode a BPSK31 signal though the build in microphone. Just hold your Android phone or tablet close to the speaker of you Amateur Radio transceiver, adjust the waterfall slider to the PSK carrier frequencies and DroidPSK will start decoding.
In transmitting mode characters can be entered trough the keyboard. 9 Macros are also available to store standard texts like “name and qth” and “station info”
Starting V2.0 DroidPSK now also includes a logbook. Callsign, Name RST etc can be easily transferred into the lookbook from the receiving screen. The logbook also includes ADIF export and import to transfer your logbook data to a PC based logging software.

DroidPSK è un programma per decodificare segnali digitali come  BPSK31. Un ottimo strumento per radioamatori
DroidPSK è in grado di decodificare un segnale BPSK31  Basta tenere il vostro telefono Android o tablet vicino al ricetrasmettitore radioamatoriale, regolare il cursore cascata per le frequenze portanti PSK e DroidPSK inizierà la decodifica.
