### Checking and Updating TQSL's Configuration Data

TQSL is driven by Configuration Data that defines

- Bands
- Modes
- Propagation Modes
- Satellite Names
- DXCC Entities
- Primary Administrative Subdivisions (e.g. US States, Canadian Provinces, Russian Oblasts)
- Secondary Administrative Subdivisions (e.g. US Counties)

Occasionally, the ARRL releases updated versions of TQSL's Configuration Data.
