Diagnosing LoTW

There are only three things to check when diagnosing TQSL.

1- Do you have the latest version of the TQSL software? 

2- Does the certificate in your computer match the certificate in the Logbook of The World system at ARRL? 


3- Do you have a station location in TQSL with the correct geographic information for your operations?


If these three things are "OK", Then you should be able to use TQSL to sign and upload your logs.

Click here to download the TQSL Diagnostic Procedure.

This is a simple process involving a few mouse clicks.

If your system fails the diagnostics download instructions to repair. 

  • You will download and install the current version of TQSL.
  • Delete the problematic certificate.
  • Request a replacement certificate.
  • Postcards or license documents will not be required to get a replacement call isgn certificate.
  • Replacement call sign certificates will be processed the same business day.
