Transatlantic Tests


The early 1920s saw the dawn of international amateur radio. A series of significant milestones led over some five years from no amateur transmission ever having been heard on another continent, to intercontinental two-way communications becoming commonplace.

The RSGB are commemorating these historic events by encouraging everyone to get on the air to make QSOs – focusing particularly on December 2022.
