I discovered that an alarming number of LoTW users are not sending their locator information during uploads to LoTW. There are also a few that are sending incorrect locator information.
The LoTW system does not use the “locator” info provided in the ADIF file. It uses the information that was provided by the user during the creation of the profile (certificate) used for signing the ADIF file.
The LoTW confirmations with absent or incorrect locator info creates a huge problem for those who are chasing VUCC awards.
I was very fortunate to come across the following info on K2DSL blog site.
I am sure you all agree it is very easy to sort out this issue if the above steps are followed.
