ARRL Logbook of The World® (LoTW®) returned to service July 1, 2024. It had been offline as part of a systems service disruption.

As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly.

We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected.

The annual Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) Workshop, funded by the National Science Foundation, ended recently in San Diego, bringing together a group of scholars from the ionospheric science community. This year, HamSCI (Ham Radio Science Citizen Investigation), a collaborative group of amateur radio enthusiasts and researchers, demonstrated significant contributions to the event, highlighting the distinct role of amateur radio in advancing scientific understanding.

HamSCI’s Notable Contributions

During the event, HamSCI members presented 11 research posters and 6 oral presentations on a variety of topics related to ionospheric science. Their research not only covered a broad range of interests while recognizing the expertise of the amateur radio community and its ability to contribute to cutting-edge scientific space physics research.

Teachers are gathered from around the United States to learn about amateur radio, and how to use it in their classrooms as part of science, technology, engineering, and mathematics (STEM) education. The 2024 cohorts of the ARRL Teachers Institute (TI) on Wireless Technology have begun.

The first group members for the year are each returning teachers participating in the second round of learning, TI-2.
