Ham radio operators often launch high-altitude balloons to carry amateur radio payloads into the stratosphere. These balloon flights are a popular way to experiment with radio propagation, track telemetry, and test equipment at extreme altitudes. Many hams use these projects for scientific exploration, educational outreach, and to achieve impressive DX contacts from the edge of space, often combining amateur radio with scientific data collection.

This category provides resources for planning and executing balloon launches, including details on payload design, antenna projects, and tracking systems. Operators can find information on using APRS for real-time tracking, as well as guides for receiving data from radiosondes. There are also resources from groups like AMSAT and Arizona Near Space Research, which share launch announcements and technical insights for successful high-altitude amateur radio activity.
