The European Ros Club issues the Worked Grid Argentina award for working stations in 5 different grid squares that cover Argentina. But there’s much more to the program than just that. You can receive additional awards for every 5 or 10 additional squares up to the maximum, which appears to be 120. That adds up to 13 different certificates.

But you can dive even deeper into the program by chasing Argentine grids on individual bands from 160M through 6M. Thus, there are over 150 certificates that await.
The certificates each include a grid overlay of Argentina and the emblem on the country’s flag. A large photo of a site within the country varies depending upon the number of grids contacted.
To apply for the Grid LU Award, and all other ERC awards, you must install the UltimateAAC application on a Windows machine. That application scans your WSJT-X ADIF log file and will inform you when you’ve qualified for the award at various levels. ERC issues the award in digital form only (JPG or PDF) with no printing or shipping costs. In fact, the award is completely free, like all of their other awards.
