16 On November 2020, the version 2.3.0RC2 of the well-known program for digital communication types WSJT-X (author Joe Taylor, K1jt) was published. This version - "Release Candidate" - precedes the release of the final version. Already now we can talk about the innovations of version 2.3. What changes will be brought to version 2.3?

Issue 2.3.1 dated March 26, 2021

This release WSJT-X 2.3.1 The main accessibility contains an updated user guide with a description of the new FST4 and FSR4W modes, as well as examples in the form of .WAV files and textbooks on their decoding. This issue also eliminates many errors and kickbacks found from the date of version 2.3.0, including the following:

When transferring the Multicast traffic to the UDP server, it is checked that the Loop-Back interface is used, and no others are selected
The problem has been eliminated in working with files that caused an endless cycle ("freezing" - approx.) During the launch of the program
Separation of the PTT transmission port is changed to the opposite - with the aim of overall use of non -Hamlib control using CAT, in a combination with direct control of the PTT port.
Decoders FST4 and FST4W are allowed to continue decoding after the first successful decoding, when the negative values of NB are used to try many Nb values
Fixed a defect in an automatic sequence during QSO, especially when responding to a final message. In-way, double click on a second message does what is needed.
The rollback that led to the unintentional termination of the EU VHF Contest by using the MSK144 type has been eliminated.
The defect with an incorrect entry in the radio communications magazine is eliminated digital FT4 and the APRIORI (AP) decoding mode.
The error of saving WAV files has been eliminated.

Issue 2.3.0 dated February 2 2021

WSJT -X 2.3.0 is the release of the main accessibility (General Availability Release), which adds new digital modes of FST4 and FST4W with the elimination of many errors. See for detailed information a description for versions 2.3.0RC below.

в режиме FST4/W отключено ограничение формы сигнала в начале и конце передачи, когда установлен переменная FST4_NOSHAPING=1. Так же работает для режима FST4SIM.
Added time stamps to diagnostic errors to help diagnosis.
The error has been eliminated, which led to the emergency completion of the process of slow mode JT9.
The CTY.DAT file is updated.

Improvements in version 2.3.0 RC4 dated January 26, 2021

This release is a "plug" between the releases, while the important changes in Hamlib are checked.
Also, the following opportunities were removed from the issue to eliminate defects:

Changes in the behavior of the WSPR Command Line Tool utility - uses the current launching directory to save if the directory is not specified to save data.
Translations of the WSJT-X interface into other languages.

Improvements in version 2.3.0 RC3 of January 6, 2021

Improvements in the decoder of a new digital mode for medium and long waves - FST4W:

The sensitivity on the channels with fading of the signal is increased, the frequency of the appearance of erroneous decoding is reduced
FST4W uses messages 50 bits long and a control amount (CRC) 24 bits. Data 74-bit messages with CRC are encoded in a 240-bit word. The accepted messages are deciphered by various decoders: a “trusting propagation” (BP) and B “Ordered Statistics” (Ordered Statistics Decoder - OSD). (...)
FT8 - the emergency completion of the program caused by a double click on the waterfall with the purpose of decoding while performing the reception/transmission interval.
Fixed the color scheme in the dark topic.
The reports that correspondents send by other stations will no longer be recorded in the error journal.
The message about the status (sent to the server) by UDP now includes the current message to the program.
An example of a configuration diagnostics journal has been attached
Local Date settings to the fields of QSO magazine were applied
Improving the size of the entrance buffers and sound output.
In WSPR mode, the correct completion of the work occurs if the data directory does not exist
Added a new WSJTX_App_VERSION utility for printing a line of the application
The regression was eliminated, which led to the choice of incorrect working frequency
The regression was eliminated, in which there was a problem with the beginning of QSO with the "Best S&P" mode on.
improved compatibility with Debian 9 - the packages required for installation
Removeed regression with lost time cliches in the All.txt file
Hamlib_Settings.json file settings now allow you to work only with “only transmission” configurations,
therefore, an optional separation of PTT transmission during RTS and DTR signals can be allowed.
Improving the size of the program window and the placement of control elements.
The regression was fixed, in which there was a problem on the QSO allocation mode unloaded on Lotw (previously supported support for OpenSSL libraries).
The defect that caused the recognition of some callsigns 2/1 is eliminated incorrect.
Several updates of international interface translations.

Improvements in version 2.3.0 RC2 of November 16, 2020

This release of the program corrects errors found in version 2.3.0 RC1 and adds some new functionality, which was not included in 2.3.0 RC1 due to the time of publication of the version.

New in version 2.3.0 RC2:

The "Passing Samples" window is removed when recording sound. Warning and sound errors are now written to the WSJT-X system log.
FS4W spots on the WSprnet.org website will be supplemented so that the server can recognize the mode in which the spots are transmitted. Thus, spots on WSprnet.org are now not limited to sections of ranges for WSPR mode.
The new internal system and program mechanism for recording magazines allows you to record information about messages such as tracing, debugging, information, warnings, errors and fatal errors. Details and filtering of messages is set by the user using a configuration file. Without a configuration file, an entry is made in a simple journal with information only with information messages, warnings and errors. The automatic rotation of the error log was implemented to restrict the use of disk space.
Так как некоторые пользователи используют неправильные multicast IP-адреса для их серверов взаимодействия, изменено поведение по умолчанию для программы - теперь отправляются лишь multicast UDP датаграммы к сетевому интерфейсу loop-back.
Users who require UDP messages to achieve other hosts using the WSJT-X protocol should now configure WSJT-X to send the UDP datigrams to the corresponding network interface, and use a properly organized group address for a multi-stroke on their application server. If you are not sure which address is used for a cartoon, then 224.0.0.1 (or FF02 :: 1 if IPV6 is used) is a safe choice.

Improvements in version 2.3.0 RC1 dated September 28, 2020

Version 2.3.0 RC1 is an update to the Beta version, which offers two new digital modes specially designed for long and medium waves.

FST4 is a bilateral QSO, FST4W - this is a mode similar to WSPR programs (to study passing) ..
Both modes offer many points for the sequence of "transmission - reception" - the duration and threshold of the sensitivity of decoding, which descends below -40 dB. Preliminary tests show that these modes often exceed intercontinental distances in ranges of 2200 meters and 630 meters. Further details and tips on the communication procedure can be found in "Quick-Start Guide to FST4 and FST4W", located on the WSJT website.

Being a release of beta-quality, version 2.3.0 offers an update of the program with many new features, capabilities, and correction of defects:

New FST4 and FST4W modes aimed at the ranges of long and medium waves.
Improved detection of the noise boundary for a more accurate assessment of the signal-shum parameter.
On the waterfall and a 2D spectrum when hovering a mouse, a floating message occurs indicating the frequency displacement, under the mouse cursor ..
Based on the feedback from users, the method of compensation for the Doppler effect of "ON DX Echo" has been improved. The main functionality has not changed. See the user manual (chapter 8.1) for more detailed information.
Improved algorithm "User_Appal", which serves to initialize the mode of changing the WSPR Band Hopping ranges.
A decoded QSO message is made more compact (compressed) to make the added information more readable without the need to scroll the window.
Added option for recording the radio wave distribution mode in the posts of the hardware magazine
(The QSO magazine unloading file) satisfies the requirements of Adif 3.1.1.
Implementation of the connection to PSK Reporter using TCP/IP for very bad Internet connections is implemented.
Существенное переписывание интерфейса для подключения к PSK Reporter с целью уменьшить объем передаваемых данных.
Удалены сгенерированные сообщение с закладки №2
Улучшения удобства работы с пользовательским интерфейсом программы
Тонко изменяемые опции скорости декодирования для улучшения пользовательского опыта при использовании программы на одноплатных компьютерах, таких как Raspberry Pi.
