WSJT-X 2.2.0 – Release 02 June 2020

Update WSJT-X 2.2.0

– Significant improvements to the decoders for FT4, FT8, JT4, JT65, and WSPR.

– New format for “EU VHF Contest” Tx2 and Tx3 messages When “EU VHF Contest” is selected, the Tx2 and Tx3 messages (those conveying signal report, serial number, and 6-character locator) now use hashcodes for both callsigns.

This change is NOT backward compatible with earlier versions of _WSJT-X_, so all users of EU VHF Contest messages should be sure to upgrade to version 2.2.0.

– Accessibility Keyboard shortcuts have been added as an aid to accessibility: Alt+R sets Tx4 message to RR73, Ctrl+R sets it to RRR. As an aid for partial color-blindness, the “inverted goal posts” marking Rx frequency on the Wide Graph’s frequency scale are now rendered in a darker shade of green.

– User Interface Translations have been enabled. Translations are now available for Catalan, Spanish, Japanese, Chinese, and Hong Kong Chinese.

Additiional languages will follow, when available. Note that UI translation is automatic, based on your system primary language. If you do not want the WSJT-X UI translated to your local language then start WSJT-X with the ‘–language=en’ command line option: wsjtx –language=en

If you wish to contribute by authoring WSJT-X UI translations please join the new discussion group (, where help from other translation authors and coordination with the development team is available.

– Minor enhancements and bug fixes “Save None” now writes no .wav files to disk, even temporarily.

An explicit entry for “WW Digi Contest” has been added to “Special operating activities” on the “Settings | Advanced” tab.

Contest mode FT4 now always uses RR73 for the Tx4 message. The Status bar now displays the number of decodes found in the most recent Rx sequence.

The “Highlight Callsign” UDP message has been enhanced to allow clearing of old highlighting for a specified callsign. Please note a recommended restriction on the use of this message in the documentation here:

– Hamlib – this library which we use for direct rig control has had many defect repairs and enhancements, we thank the contributors to that project for their work.

Updat JTAlert 2.16.5 – 08/05/2020

Includes Callsign database file version 2020-05-08 (2020-May-08)


– WSJT-X 2.2.0 FT8: Callsign clearing time adjustments for early decodes.

– Log QSO times: Default setting for recording seconds in QSO times changed from off to on. This will apply to new JTAlert installs, existing users will need to manually enable the setting if they want seconds recorded.

– /MM callsigns: No longer alert on DXCC, CQZone or Continent.

– https queries: Lookup of Callsigns online for text messages and available update checks changed from using https to http. This was done due to a number of Win7 & Win8 users with older OS installs, lacking modern SSL support, failing to correctly establish SSL connections.

SWISSLOG For Windows – Update To Version 5.99g

Version  5.99g 19/04/2020


This version includes the following corrections/enhancements:

  • NEW: Logbook view: now the Custom filter will appear in the selected language. The EQUAL operator accepts the following wildcards:
    • *:  represents zero, one, or multiple characters. Example: EA3* applied to the callsign field will list all callsigns starting with EA3 and any suffix, *SOTA will list all callsigns having SOTA in the suffix, *70*% will list all callsign starting or having 70 in the middle of callsign, etc
    • ?: represents a single character: Example: E?3G? will list all callsigns like EA3GC, EL3GA, EM3ZZ, EA?GCV will list EA1GCV, EA3GCV, EA8GCV, etc.

You can also mix both wiildcards: ?A* will list all callsigns like EA3GCV, 1A0KM, 3A2AC, etc. As you can see, it offers endless filtering possibilities!

  • NEW: World map: added CAT button to automatically read the transceiver band and select it in the DXCC and Grids fields. Also added a MODE drop list to select the DXCC/Grids according the selected mode. It also includes the following report modes: PHONE, MIXED, DATA and IMAGE. Please read World Map chapter to know more details.
  • NEW: DX message window / Band maps: added an option in the popup menu to disable the warning to save QSO or ignore if adding a QSO from a spot and a call already exists in the Add QSO window without saving.
  • NEW: Added European ROS CLub (ERC) for membership panel and new statistic
  • NEW: Comments field: If you upload QSOs to eQSL, you can differentiate the text added as message in your eQSL card from regular QSO notes. Simply add QSLMSG: in the Comments field with the text you want to display in your eQSL card. Example:

This text is your QSO comments. QSLMSG: This text will only be displayed in your eQSL card

“This text is your QSO comments” will be added as Notes if you upload QSO to Club Log, HAMLOG, HRDLOG, HAMQTH or QRZ. “This text will only be displayed in your eQSL card” will only be sent to eQSL.

IMPORTANT: QSLMSG: tag must be uppercase and located at the end of other QSO notes! If you don’t set the QSLMSG: tag then all comments will be sent to all configured online logbooks.

    • NEW: WSJT-X / JTDX Band Map: changed spot lifetime from minutes to seconds. This will allow you to set values to display only one decode period (15 seconds for FT8 or 8 seconds for FT4). Current minute values are converted automatically to seconds at startup.
    • NEW: Added the DXCC field to read from the following Callbook databases: QRZ, QRZCQ and HAMQTH. Very useful for those users not using the Query and set Club Log DXCC option (which prevail over this function). Redesigned the “Field Copy Instruction” tab in the Callbook options.
    • NEW: Users retrieving data from HAMQTH/QRZCQ: the DOK will be filled out automatically if QSO partner has assigned the DOK in the profile and the County field (Sub Region) has been checked in the Field Copy Instruction in the Callbook CD / Internet databases option
    • NEW: Statistic Quick Info window: Added the SubRegion field in the “Previous QSO” listing.
    • NEW: Added IARU 1, IARU 1 28MHZ, IARU 3 and ERC statistics.
    • NEW: Added DXCC Challenge award for statistic view/reports including modes CW, PHONE, DATA, ALLMODES.
    • NEW: CW Type: when activating CW Type buttons in Add QSO window, pressing the CW Type button will restart Cw Type. This is mandatory to do if you have changed macros in Swisslog to reflect changes in CW Type.
    • NEW: Logbook view: I have added a full set of new and very interesting queries! You can now check for:
      • DXCC/WAS/WAZ/WPX are confirmed by QSL and not confirmed by LoTW/eQSL by all possible confirmation combinations (LoTW or eQSL).
      • DXCC/WAS/WAZ/WPX/WAE are confirmed by all possible confirmation combinations (QSL, LoTW or eQSL).
      • Missing DXCC/WAS/WAE all bands/5 Bands all modes
      • Worked DXCC/WAS/WAZ/WAE all bands/5 Bands all modes

Queries titled for specific bands/modes are intended to be used as template for advanced users who want to check for other bands/modes (simply edit the query and replace the band/mode you need then save it with another name). Check out on the following Queries subfolders for the new queries: DXCC, WAZ, WAS, WPX, WAE.

  • NEW: Swisslog installer: added an EULA (End User License Agreement).
  • Improved WSJT-X Band Maps: code rewritten to improve significantly performance! This should solve all freeze issues after a while working with high activity on bands.
  • Improved: Band Maps: improved overall performance.
  • Added: Telnet server list: EA3CV-2. In order to use latest Telnet server list, you have to delete the file Telnetservers.bin and rename Telnetservers_orig.bin to Telnetservers.bin. Please note that doing this you will lose the auto start settings and all your previous changes to other servers, so you will have to configure it again.
  • Corrected: WSJT-X Band Map: if user changed the Grid statistic it was not saved for the next session.
  • Corrected: WSJT-X UDP Settings window: resized to fit in the minimum screen resolution recommended for Swisslog (1024×768)
  • Corrected: LoTW sync: web passwords including special characters like ‘&’, ‘<‘, ‘>’, ‘#’, etc caused LoTW sync to not download QSOs/QSLs.
  • Corrected: LoTW sync: Swisslog won’t ask user anymore to assign new LoTW ADIF fields to Swisslog fields if found during LOTW synchronisation (i.e: APP_LoTW_RXQSO, APP_LOTW_RXQSL…)
  • Corrected: LoTW/eQSL sync: QTH locator from LoTW/eQSL will be set in the QSO if the QTH locator field is empty or if QTH locator to import has 6 digits and the QTH locator field has 4 digits matching the Maidenhead.
  • Corrected: Club Log/HAMQTH: passwords including special characters like ‘&’, ‘<‘, ‘>’, ‘#’, etc didn’t work.
  • Corrected: eQSL sync: the Error list tab didn’t list any QSO, only a line indicating the file containing errors. In order to receive again a full report, it’s very important to perform a full resynch of all your QSOs in eQSL by setting a last synch date before your first QSO in the logbook (or 01/01/1900).
  • Corrected: Import QSO from another Swisslog DB: QSOs were not assigned to any MyQTH
  • Corrected: TrueTTY: some fields were not passed to Swisslog.
  • Corrected: TrueTTY/CW Type: shortcuts for macro buttons (Shift+Ctrl+F1-F2) caused triggering other associated functions to hot keys (such F1 Help, Ctrl+F4 close current window, etc).
  • Corrected: Logbook view: error message “Capacity of list is out of bounds” when using certain printers. If view takes a lot to open when opening any logbook view, edit the SWISSLV5.INI file and add the following key in the COMMON section: DisableDXPrinter=1
  • Corrected: Realtime logging to QRZ: the QRZLOGID field was not set.
  • Corrected: Flex Radio support: mode was set to a number when changing mode on Flex Radio
  • Corrected: FLDIGI link: using FLDIGI versions from and higher in countries having a comma as decimal separator, the frequency was not passed into Swisslog.
  • Corrected: ADIF import: if QTH locator to import had 4 digits the Distance field was set to 0
  • Updated: World Map: added latest IOTA references into the IOTA layer
  • Corrected: HAMLOG: password length limited to 10 characters (maximum length allowed by HAMLOG).
  • Corrected: Rotor control: The Hy-Gain DCU-1 option didn’t work for DCU-2/DCU-3. Now should work for all.
  • Corrected: WinKeyer support: the [L] command used in macros to LOG QSO didn’t work
  • Corrected: SOTA Update: changed URL link
  • Corrected: Save desktop at exit main option will be checked by default in new installations.
  • Corrected: AGCW update: changed link and file format from XLS to CSV
  • Corrected: Refresh view automatically logbook view option will be checked by default in new installations.
  • Corrected: Register QSL cards: Azimut was not displayed correctly in the detailed view of the QSO
  • Updated country table. THANK YOU VERY MUCH to Erik, EI4KF.

– minor changes to Spt/Menu controls view, reversed broken Pwr slider appearance
– ‘fusion’ is set as default JTDX style, ‘-style=windows’ key in JTDX launching shortcut will switch ‘fusion’ style off
– crossband 160m band operation with Japan is moved to option for all scenarios but EU-JA QSO, by default crossband is enabled, can be switched off in Misc tab of main window UI
– patch to possible marker misalignment in QSO RX frequency messages window triggered at double click on message
– messages like ’73’ shall not be treated as ‘reply to other’ while correspondent using multislot transmission
– prevent calling on Fox frequency when user resuming TX after three unsuccessful TX attempts
– added optional broadcast of logged QSO ADIF message to secondary UDP server, the same message format as in WSJT-X being used, controls are in ‘Reporting’ tab of configuration settings, same message format as in WSJT-X is used
– ‘Logged ADIF’ UDP message addressed to primary UDP server now is optional, can be activated in ‘Reporting’ tab of configuration settings
– main frequencies introduced, marked in frequency list by asterisk. At mode change JTDX will be selecting main frequency rather than Fox frequency.
  Some frequently used DXpedition frequencies added as default values in the frequency list. Main mode&band frequencies can be deleted by user, ‘reset frequency list’ will recover default frequencies
– six-pass SWL option is withdrawn from FT8 decoder
– implemented up to 3 cycles of FT8 decoding (each cycle has three decoding passes, six-pass SWL mode was two cycle decoding), one cycle is set by default, two or three cycles can be activated independently for operation and SWL modes.
  Withdrawn multicycle FT8 decoding dependency on number of running JTDX instances. Still there shall be more than 3 threads used in FT8 decoder to get multicyle decoding active in SWL mode.
– Hint button shall be switched on in FT8 mode by default(first launch of JTDX or if .ini file is deleted)

– patch for counters when doubleclicked on call which is not in history (no CQ or 73 like messages received from this callsign), first counter did not work in such scenario
– ALLCALL7.TXT is now being used for filtering false FT8 decodes with support of 7-char Australian callsigns, ALLCALL.TXT is not used anymore
– filtering false decodes: faster callsign search in the ALLCALL7 based list via block data access
– added checking for false FT4 decodes starting from “TU; “
– added SNR and DT criteria for checking FT8 false decodes containing ” R “
– one more attempt to eliminate ‘CQ DE AA00’ false FT8 decode, it was likely coming from OSD decoder with AP mask in presence of strong signal on the band
– LoTW users list is updated, cty.dat file is updated to version CTY-3004
– ALLCALL7.TXT is updated to 111851 callsigns
– rc148 is built with modified Hamlib code v20200123
