This page briefly documents Changes and New Functions added to the various releases.

Version 5.117 12/06/2026

This version includes the following corrections/enhancements:

NEW: Transceiver control: added support to HAMLIB NET.
NEW: Added Diploma fields from 21 to 30 to allow more new awards.
NEW: Added Towers On The Air (TOTA) statistic on field Diploma 21 and an option to update the reference list from the official TOTA website.
NEW: Added Worldwide Bunkers On The Air (WWBOTA) statistic on field Diploma 22 and an option to update the reference list from the official WWBOTA website.
IMPROVED: Overall performance when receivng data from WSJT-X, JTDX, etc specially after long running sessions where Swisslog became slower.
IMPROVED: WSJT/Cluster Band Maps: improved performance and processing speed. Previously the station details were not displayed most times when placing mouse over the station. After long Swisslog session periods band map displayed stations which were decoded one minute or more ago. Now works faster and more stable than before.
Corrected: QSO Entry: when entering text in the "Operator" field, the cursor always moves back one step to the beginning.
Corrected: QSO Entry: if the QSO Entry window was closed, when forcing editing a QSO from a Logbook view having notes in the Notes field, the Notes field was empty after the QSO Entry window was opened.
Corrected: QSO Entry: when user changed the font for the active window, changes were not applied to Note field, Address and Note fields from the Station tab.
Corrected: Tools / Export WSJT-X Log: FT2 mode was not included in the mode list.
Corrected: Tools / Update awards information / Update DEE reference list: field position was truncated when a comma was found in the middle of a field causing a wrong field allocation.
Corrected: Tools / Update awards information / Update AGCW members list: "20.04.2026 is not a valid integer value"
Corrected: Yaesu FTX-1: mode was not set in the QSO Entry window.
Corrected: QSO entry clock: local time for QSO partner was wrong in countries where DayLight Saving Time is applied. The same happened if the Partner time option was checked in the Propagation Prediction function.
Corrected: PstRotator: beaming was not set from Swisslog. Errors when reading elevation if the rotor interface window was used.
Corrected: WSJT-X Band Maps: no stations displayed if none Dx window / Band Map is open.
Improved: DX Windows / Band Maps: when double clicking on a spot, selected actions (specially Log QSO) took many seconds to be executed. If turn rotor was one of the actions, sometimes was not executed.
Corrected: Statistic Quick Info: statistic values were not refreshed after saving/deleting a QSO thus showing the same statistic status until restarting Swisslog.
Updated country table. THANK YOU VERY MUCH to Erik, EI4KF.
Updated: 30MDG, AGCW, ARLHS, BCA, CLUBLOG, CWOPS, DCE, DCI, DEE, DEFE, DERESP, DFCF, DIG, DME, DMVE, DOK, EA QRP, EPC, eQSL, ERC, FCC, FISTS, FOC, FT8DMC, HSC, IOTA, LYNX, LOTW, LLOTA, MF, NDG, POTA, RDA, SKCC, SOTA, TBDXC, TEN TEN, URE, USI, WCA and WFF statistics on 12/06/2026.

Version 5.116 16/04/2026

This version includes the following corrections/enhancements:

NEW: Special for LLOTA HUNTERS!: Swisslog checks every minute the current LLOTA activators from the LLOTA website (https://llota.app/api/public/spots). This offers the following very interesting features:
- Added LLOTA statistic on field Diploma 20 and an option to update the reference list from the official LLOTA website.
- Add QSO: LLOTA field will be automatically filled out if callsign is found in the list of current LLOTA activators.
- DX message and Band Map windows: you can add the LLOTA statistic to know current status of this award for spots in realtime. No need that LLOTA reference is included in the spot comment to know this! LLOTA reference is automatically added in the spot details on Band Maps.
- WSJT-X Band Maps: LLOTA reference is automatically added in the spot details. You can also use a specific LLOTA band map to quickly and easily monitor if there are LLOTA references and if you need them or not.
- Statistc Quick Views: use a specific LLOTA statistic quick view to know which bands/modes you have worked/confirmed a LLOTA reference (or if you need it) after entering a call in the Add QSO window or by clicking on a callsign from Dx windows or Band Maps.

This option is enabled by default. If you don't work LLOTA you can disable it in Options / Query LLOTA Activators.

NEW: Unicode support in the following fields: Operator, QTH, QTH-Name, Callbook fields and Notes. Now you can enter and display properly international characters (Chinese, Arabic, Cyrillic, etc.) and symbols. If you are reading data from QRZ/QRZCQ (which supports Unicode) these data was saved as ????? in the database. When entering QSOs from previously worked stations or updating data from internet databases in logbook views (QRZ or QRZCQ only), now Swisslog will automatically replace the garbage data by the proper characters in the Operator and QTH fields and also fields in the Callbook table. NOTE: for technical limitations these characters will be still displayed in Logbooks views or listings as ???? although data is properly saved in the database. Symbols are not working in the Note field neither
NEW: Support for FT2, RIBBIT_PIX and RIBBIT_SMS: added new modes and adapted ADIF import/export function to fulfill the new requirements in ADIF specs 3.1.17
NEW: CW Interfaces: added an option to select "None" if no CW Decoder software is going to be used.
Greatly IMPROVED: Tools > Update Award Info (Internet): Code has been deeply rewritten and optimized. Updating ALL lists now takes about 3 minutes only! Previously took about 1 hour!!
Added: "Print / Display 0 with a bar": Callsign field in the Register QSL Card and Callbook windows now shows zero with bar if this function is enabled.
Corrected: QSO Entry: Violation error OLEAUT32.DLL when saving QSO.
Corrected: QSO Entry: if user checked "Do not set mode from TX" and added a callsign from the DX window, this setting was disabled.
Corrected: QSO Entry: The Clear diploma fields button didn't worked well under some scenarios and some values remained.
Corrected: QSO Entry, entering EA awards references for EA stations: when you have worked many times the same station from different locations, another QTH-Name profile was selected automatically, erasing or changing the just entered reference.
Corrected: Register QSL Cards: if user enabled "Automatically set the QSL Action to" the action was not set if QSL Received/Sent was already 1.
Corrected: Logbook views > Export QSOs: when using filters typed in lowercase or using wildcards there were no QSOs to be exported.
Corrected: MRP40 logging: band was left blank when logging a contact on 13cm band (QO-100) using the transceiver control.
Enhanced: MRP40 logging: if user don't set any RST sent/received in the MRP40 Minilog, Swisslog assumes 599 in both fields.
Changed: Logbook views: improved use of wildcards.
Updated country table. THANK YOU VERY MUCH to Erik, EI4KF.
Updated: 30MDG, AGCW, ARLHS, BCA, CLUBLOG, CWOPS, DCE, DCI, DEE, DEFE, DERESP, DFCF, DIG, DME, DMVE, DOK, EA QRP, EPC, eQSL, ERC, FISTS, FOC, FT8DMC, HSC, IOTA, LYNX, LOTW, LLOTA, MF, NDG, POTA, RDA, SKCC, SOTA, TBDXC, TEN TEN, URE, USI, WCA and WFF statistics on 16/04/2026.

Version 5.115 08/01/2026

This version includes the following corrections/enhancements:

NEW: Transceiver control: Added support for Yaesu FTX-1.
Corrected: QSO Entry: when working a station which was logged previously, QTH locator was empty if user read from Callbook databases (such as QRZ) but was not a subscriber.
Corrected: QSO entry: entering a previously worked EA station, the Spanish statistics (DME, DVGE, etc), even active, were not displayed in the Diploma fields.
Corrected: Transceiver control window: option dialog was displayed partially.
Updated: 30MDG, AGCW, ARLHS, BCA, CLUBLOG, CWOPS, DCE, DCI, DEE, DEFE, DERESP, DFCF, DIG, DME, DMVE, DOK, EA QRP, EPC, eQSL, ERC, FISTS, FOC, FT8DMC, HSC, IOTA, LYNX, LOTW, MF, NDG, POTA, RDA, SKCC, SOTA, TBDXC, TEN TEN, URE, USI, WCA and WFF statistics on 08/01/2026.

Version 5.114 25/12/2025

This version includes the following corrections/enhancements:

NEW: Transceiver control window: custom buttons can be now set as double action button to allow send a command when the button is active (pressed) or inactive (unpressed).
NEW: Pivot tables: user can now add a custom filter (in SQL format) by editing the PVT file with a text editor. This is VERY USEFUL to select the QSOs for a specific year or range of dates. For instance: if you want to select the QSOs from a certain year you need to add the following line:

CustomFilter=YEAR(L_DATE) = 2023

Or a range of dates:

CustomFilter=L_DATE >= #2025-01-01# AND L_DATE <= #2025-01-31#

NEW: Spanish Regions (Comarcas) awards: Now when entering a DME reference in a EA station which belongs to Catalunya, Andalucia, Aragon, Valencia, Galicia or Castilla-La Mancha regions, the SUB-REGION field (Comarca) will be filled automatically.
NEW: Special for hunters of the Spanish Regions (Comarcas) awards: in the Tools menu there is a function to set the TPEA and Region (comarca) automatically from DME reference.
Corrected: Transceiver control for Yaesu and Kenwood: optimized to be used along other CAT software at once using VSPE to avoid conflicts or sudden Swisslog shutdown.
Corrected: Transceiver control for HRD: improved S-Meter and Tx Power readings. Mode list is adapted automatically to the selected transceiver if ICOM, Kenwood or Yaesu.
Corrected: Pivot tables: when selecting a MyQTH the following error occured and table was not displayed: Microsoft Database Engine can't recognise My_QTHID as a valid field or expression.
Corrected: Membership panel: the online query used to know if an Argentinean station is RCA member didn't worked. RCA changed the format of the response.
Corrected: Callbook databases: QTH locator were not copied into the QTH locator field under certain scenarios.
Corrected: HRDLog upload: QSOs were marked as uploaded even if an error occurred (such a wrong Upload Code).
Deleted: Membership panel: the online query to know if a French station is REF member has been deleted. REF has disabled this service for violation of EU General Data Protection Regulation (GDPR).
Updated country table. THANK YOU VERY MUCH to Erik, EI4KF.
Updated: 30MDG, AGCW, ARLHS, BCA, CLUBLOG, CWOPS, DCE, DCI, DEE, DEFE, DERESP, DFCF, DIG, DME, DMVE, DOK, EA QRP, EPC, eQSL, ERC, FCC, FISTS, FOC, FT8DMC, HSC, IOTA, LYNX, LOTW, MF, NDG, POTA, RDA, SKCC, SOTA, TBDXC, TEN TEN, URE, USI, WCA and WFF statistics on 24/12/2025.

Version 5.113 18/07/2025

This version includes the following corrections/enhancements:

NEW: TCI: added support for Thetis software 2.10.3.11 or higher. This allows to show spots in panorama with extended data including Comments, Spotter, Beaming, Continent, Country Name and spot age.
LoTW synch > No QSOs uploaded after LoTW mainteinance. The signed and compressed GZip TQ8 file generated by Swisslog was rejected by the LoTW system after their mainteinance performed from 27th June to 5th July. After being in close contact with the LoTW developers they discovered that this file, which was properly accepted by LoTW for almost 30 years, now raised a CRC error. Seems that last GZip version installed in the LoTW system is more strict than the old version which allowed some kind of errors decompressing the file. Thanks to the good predisposition from the LoTW developers they reverted this change temporarily until I could fix this issue. Fortunately, I have been able to implement a new GZip compressor in the compiler which solves this issue.

VERY IMPORTANT NOTE: All users MUST upgrade to version 5.113 not later than 31st August!. From 1st September LoTW will reject again all QSOs uploads made from Swisslog versions prior to 5.113.

WSJT-X Band Maps: band maps where data source was any of the 5 Log QSO instances, showed statistic status as if it was the band from the main instance.

Version 5.112 01/07/2025

This version includes the following corrections/enhancements:

NEW: WSJT-X / JTDX / MSHV Band Maps: Added a dropdown list to select the instance from which you want to read data. This is very useful when using several instances of these programs. Now you can use Band Maps for every instance to monitor every instance separately for the awards you need. The dropdown list shows the instance program name, current mode and band to help user to select the instance easily. You can also start TX from every band map by double clicking on CQ messages (WSJT-X). JTDX also allows to reply on any message in Misc > Accept UDP Reply Messages > Any messages.
NEW: Added COM monitor and Command tester to FlexRadio 6xxx/8xxx and FlexRadio CAT TCP transceiver options.
NEW: Transceiver control window: you can now use custom commands to control FlexRadio 6xxx/8xxxx and FlexRadio CAT TCP transceiver options.
NEW: Transceiver control options: now this windows remains "floating" over the rest to allow using the COM monitor and command tester while using other Swisslog functions.
NEW: Transceiver control for FlexRadio 6xxx/8xxxx: you can now send several commands at once from command tester or custom buttons in the transceiver window by inserting '\n' between the commands. This allows to execute several commands in a single line. Example: C0|slice s 3 active=1 tx=1\nC44|audio client 0 slice 3 mute 0
NEW: QSO Entry > SOTA field: now when entering a SOTA reference the QTH Locator will be automatically set to the SOTA reference grid. This already is applied when entering a POTA or WWFF references.
NEW: QSO Entry > DME field: when entering a DME reference for EA stations the QTH field will be set to the city name.
Improved: FlexRadio TCP CAT: reduced TCP traffic to improve performance. S-Meter values were not read. Improved code.
Improved: Kenwood and Yaesu control: reduced COM traffic and improved performance when working along with other applications using virtual COM ports with VSPE or similar.
Improved: POTA detection: POTA reference was not read in some portable stations such as W4LX/15, 3A/F5PGP and so on.
Improved: Add QSO > QTH Name field: this field is automatically handled by Swisslog and user doesn't need to pay attention to this field. However, now the name assigned to this field is more comprehensive according the field which has been changed. Previously when a Diploma field changed, normally the QTH Locator was set as QTH Name. Now if a Diploma field changes, the Diploma field reference will be set as QTH Name.
Corrected: UDP realtime logging using ADIF format: ADIF data was not v3 compliant so uploading QSO having ADIF Submodes (such as FT4, JS8, PSK31, MFSK8, etc) caused errors in certain logging applications.
Corrected: LoTW synch: LoTW doesn't recognises QSO made on SIM31/SIM63 or made on 8m band. In order to avoid error messages during LoTW synchronization, these QSO will be marked as Rejected in the LoTW status field automatically when being saved. This way will be ignored in the LoTW synch function.
Corrected: N1MM/DM780: QSOs were not saved from DM780.
Corrected: N1MM/DM780: "Band: an entry is required" error message when receiving QSOs in N1MM XML format from other software different than N1MM.
Corrected: N1MM/DM780: if an error was found reading QSO data no more data was allowed and a Swisslog restart was needed.
Corrected: QSO import: last dialog remained opened after pressing the Finish button.
Corrected: Export QSO dialog: the "View on Screen" option was disabled on Windows 11 for ADIF and Text files.
Corrected: WSJT-X / JTDX Band Maps: when a station was calling CQ POTA or CQ ASIA was not displayed on Band Maps.
Corrected: Realtime logging using ADIF format: accented characters were not converted to the regular letter (as fixed in version 5.111). This only applies to the QTH, Name and Comments fields to make content more comprehensible. Specific for German language: "ß" will be converted to "ss".
Changed: QSO import > Error / Merging list: now messages will be displayed in plain text. Rich text used previously was better visually speaking but added lot of processing time and the saved report was needed to be open with a rich text editor.
Deleted: Update ARLHS reference list: the link to download the list from official web site no longer works. I have tried to contact many times with the award manager getting a silence as response. ARLSHS list seems is not updated anymore so no need to have this option and the information table will remain as it is.
Updated country table. THANK YOU VERY MUCH to Erik, EI4KF.
