What is new in WSJT-X 2.4.0?
The main feature of WSJT-X 2.4.0 is the introduction of Q65, a new digital mode designed for minimal two-way contacts over especially difficult propagation paths. Q65 can handle Doppler spread up to several hundred Hz, making it ideal for ionospheric scatter, tropospheric scatter, rain scatter, trans-equatorial propagation (TEP), earth-moon-earth (EME), and other challenging scenarios.
Q65 uses the same message formats and sequencing as FST4, FT4, FT8, and MSK144, so you can easily switch between them depending on the situation. Q65 also offers submodes with different tone spacings and transmission durations, ranging from 15 seconds to 300 seconds. You can use a new list-decoding technique to decode messages that contain fragments of previously copied messages, or use message averaging to improve the chances of decoding weak or intermittent signals.
WSJT-X 2.4.0 also includes several other improvements and bug fixes, such as:
A new DLL version of the Hamlib library for Windows users, which allows easier updates of Hamlib bug fixes.
A better handling of the two queues in Fox mode for FT8 and FT4.
A fix for a defect with own call decode highlighting when callsigns with a common root are decoded.
A fix for a regression with missing timestamps in ALL.TXT for MSK144 mode.
A fix for a defect in the selection of working frequencies matching the current band and mode combination.
A tune up tone for WSPR band hopping mode when scheduled to transmit.
A fix for a long standing defect in per band tune and Tx power level memories.
More flexibility for inputting calls into the DX Call field, ignoring leading and trailing white space characters.

How to use WSJT-X 2.4.0?
To use WSJT-X 2.4.0, you need to have a compatible radio transceiver, a sound card interface, and an internet connection. You also need to set up your station parameters, such as your callsign, grid locator, and audio devices.
To configure WSJT-X 2.4.0, you can follow these general steps:
Basic settings and configuration
Open WSJT-X and click on File > Settings.
In the General tab, enter your callsign and grid locator in the appropriate fields. You can also choose your preferred language and time source.
In the Radio tab, select your rig model, serial port, baud rate, data bits, stop bits, and handshake mode. You can also enable CAT control, PTT control, split operation, and rig power control if supported by your rig.
In the Audio tab, select your input and output sound devices. You can also adjust the sample rate and audio levels.
In the Reporting tab, enable network services if you want to send and receive spots from PSK Reporter, WSJT-X UDP Server, or N1MM Logger+. You can also enable logging to a local file or an online service such as LoTW or eQSL.
In the Frequencies tab, you can add or edit working frequencies for different bands and modes. You can also enable band hopping if you want to switch bands automatically according to a schedule.
In the Advanced tab, you can tweak some settings for fine tuning your performance, such as decoding depth, Rx frequency tolerance, Tx delay, Tx watchdog timer, and special operating modes.
Click OK to save your settings and close the window.
How to choose and operate different modes, especially Q65
To choose a mode in WSJT-X 2.4.0, you can click on the Mode menu and select one of the options. You can also use keyboard shortcuts (F1-F9) to switch modes quickly.
To operate a mode in WSJT-X 2.4.0, you can follow these general steps:
Select a working frequency from the drop-down list or enter it manually in the Frequency box. You can also use the Up and Down arrows to change frequency in small steps.
Select a submode from the drop-down list if applicable. For example, for Q65 mode, you can choose between A15 (15 seconds), B30 (30 seconds), C60 (60 seconds), D120 (120 seconds), E300 (300 seconds), F60-120 (60-120 seconds), G30-60 (30-60 seconds), H15-30 (15-30 seconds), I10-20 (10-20 seconds), J5-10 (5-10 seconds), K2-5 (2-5 seconds), L1-2 (1-2 seconds), M0.5-1 (0.5-1 second), N0.25-0.5 (0.25-0.5 second), O0.125-0.25 (0.125-0.25 second), or P0.0625-0.125 (0.0625-0.125 second). The submodes differ in the tone spacing and the transmission duration, which affect the bandwidth and the sensitivity of the mode.
Adjust the Tx and Rx frequency sliders to set the desired frequency offset from the dial frequency. You can also use the mouse wheel or the Shift and Ctrl keys to change the frequency in small steps.
Click on Monitor to start receiving signals and decoding them. You will see the decoded messages in the Band Activity window, color-coded by type and age. You can also see the waterfall display of the spectrum and the signal strength in the Wide Graph window.
Click on Enable Tx to start transmitting signals. You can either use Auto Seq to let WSJT-X automatically sequence your transmissions, or use Manual Seq to control them yourself. You can also use Fox/Hound mode to operate as a DXpedition station (Fox) or a DX chaser (Hound).
Click on a decoded message in the Band Activity window to select a station to contact. You will see the station's callsign, grid locator, signal report, and other information in the Rx Frequency window. You will also see your own message in the Tx Frequency window, ready to be transmitted.
Click on Log QSO to log your contact after completing it. You can enter additional details, such as comments, QSL status, and confirmation method, in the Log QSO window. You can also upload your log to an online service if you have enabled it in the settings.
How to monitor and report signals using WSPR and other tools
WSJT-X 2.4.0 also allows you to monitor and report signals using WSPR and other tools. WSPR is a mode that enables you to probe potential propagation paths using low-power transmissions. You can use WSPR to test your antenna performance, compare different propagation modes, or just explore the radio spectrum.
To use WSPR in WSJT-X 2.4.0, you can follow these general steps:
Select WSPR mode from the Mode menu or press F8.
Select a band from the drop-down list or enter a frequency manually in the Frequency box.
Click on Monitor to start receiving WSPR signals and decoding them. You will see the decoded messages in the Band Activity window, along with their callsigns, grid locators, frequencies, signal reports, and drifts. You will also see a map of the stations you have heard or have heard you in the Map window.
Click on Upload Spots to send your decoded messages to the WSPRnet database, where they can be viewed by other users. You will need to enter your callsign and grid locator in the settings before uploading spots.
Click on Enable Tx to start transmitting WSPR signals. You can adjust your Tx power level and Tx percentage in the settings. You can also enable band hopping if you want to transmit on different bands according to a schedule.
Besides WSPR, you can also use other tools to monitor and report signals using WSJT-X 2.4.0, such as:
PSK Reporter: A website that collects and displays real-time reports of digital mode activity from around the world. You can enable PSK Reporter in the settings and view your own or other stations' reports on [22](
WSJT-X UDP Server: A program that runs on your computer and receives UDP packets from WSJT-X containing decoded messages. You can use WSJT-X UDP Server to feed data to other applications, such as JTAlert or GridTracker. You can download WSJT-X UDP Server from [23](
N1MM Logger+: A logging program that integrates with WSJT-X and supports various contest modes, such as RTTY Roundup, FT Roundup, VHF Contest, and more. You can use N1MM Logger+ to log your contacts, score your points, and generate reports for submission. You can download N1MM Logger+ from [24](
