The FT4 Digital Mode Club (FT4DMC) issues for the Grid Square Award (GSA) for working stations in at least 100 different Maidenhead Grid Squares around the world. You must make all contacts using the FT4 digital mode.

After working 100 grids for the initial award you can obtain additional awards for working 500, 1000, 2000, 3000, 4000 and 5000 grids.
The GSA certificate sports a large map of the world with grid fields overlaid. Grid Fields are the larger divisions of the world represented by the first two characters of a Grid Square. For example, EM from EM10.
To apply for GSA, and all other FT4DMC 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. FT4DMC 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.
