The Grid Chaser’s Atlas of the DX World is a series of Excel worksheets based on the Maidenhead Grid Locator system. The Atlas documents the grids occupied by all 340 countries / entities recognized by DX groups and most logging services.

The Atlas is intended for DXers and shortwave listeners interested in documenting countries and grids where they have made QSOs. A supplemental section is included: The Grid Chaser’s Atlas for Worked All States. It is intended for hams working toward Worked All States awards.

The Atlas worksheets are not linked to any logging programs. Updating to indicate grids contacted is a manual process by the user. Included with the Atlas are two additional files: Introduction.docx and Introduction.pdf. The two files are identical in content. Be sure to read one of them for guidance before working with the Atlas.
