Hello Jordi
Have you heard about issues between SWLog and LOTW after the upgrade off LOTW

Not able to Upload from 5.111 and 5.112 after upstart off LOTW this week
.ADI as well as .tq8 files are in the system and QSO are marked correct in Logbook but dont show up in LOTW
No warning or other thing

I have exactly the same problem.....
The same here. No new QSO's uploaded - no Error displayed. Seems to download old QSO's.

Hi all,

Sorry for the delay but I have been on vacation during a week. I have been in close contact with the LoTW developers because after the LoTW mainteinance the Swisslog synch failed to upload files. Seems that after LoTW has upgraded their software the TQ8 file generated by Swisslog gives a CRC error when decompressing. This file has been working for about 30 years but seems the new version of their compressor is giving this error now. I have achieved that they can revert this change temporarily until I can adapt Swisslog to the new requirements and release a new version. You can use the LoTW synch as usual but in order you can upload again the QSO during the LoTW off period, you have to do the following steps. IMPORTANT: all users who have uploaded manually the QSOs from this period by using TQSL, DON'T NEED to do this! Simply execute the LoTW synch as usual. Other users follow these steps:

  1. Download this file: https://www.swisslogforwindows.com/Downl...TW-fix.zip
  2. Unzip this file and extract the LoTW fix.sql into the C:\Swisslog\Scripts folder
  3. Run Swisslog then go to Tools / For experts only > Execute SQL script then select this file from the Scripts folder and accept all confirmation messages.

With this operation the LOTW Status field will be set blank in all QSOs in the date range from 27th June and 5th July (included) to allow the LoTW synch function to upload again these QSOs. After executing this script go to Tools /  LoTW synchronization, press the Synchronize LoTW and afterwards the Start sync button.

Hi Jordi,

the LOTW_Status, LOTW_SEND and LOTW_Received fields are still empty.
I do not see an EXPORT file either.
Hi Rainer,

It's working perfectly here, review your certificate, password and station location settings. The script leaves blank the LOTW Status field and when you start the LoTW synch function (automatic mode) as explained above) the LOTW Status field should be changed to Uploaded, Accepted or Confirmed and you should see these QSO in your LoTW account (Your account / Your activity). Review the QSO End date in your certificate.

Somehow the QTH (Canary Isllands) got lost in the Configuration.
But why is there no error message when the upload does not work ?

tnx & 73, Rainer
Rainer,

This worked during 30 years with no issues. It was not expected that LoTW now after the mainteinance work won't recognise the file uploaded by Swisslog. I'm working in a new version fixing this to fullfil the new requirements.

Hi Jordi,

I now get an error: Error: File CANARYISLANDS_20250716.tq8 data error
