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 will commemorate these historic events by encouraging everyone to get on the air to make QSOs – focusing on December 2021 and December 2022. Full details of the how you can participate will be published here.

Special Events and Activities

RSGB, ARRL and our members are organising some great on-air activities to celebrate the achievement of transatlantic communications by radio amateurs one hundred years ago.

The RSGB and the ARRL The National Association for Amateur Radio® in the US have announced joint events to celebrate the achievement of transatlantic communications by radio amateurs 100 years ago. The press release can be read here.
