The Olde Towne Middle School Radio and Technology Club from Ridgeland, MS is proud to be launching what is most likely the state’s first near-space balloon from a non-college school! The launch status is GO for right now and the weather is looking breezy but good. The students rigged up a practice payload chain today and everything was tested and is working great! We want reception reports from both HF and VHF modes. We are going to plot all reception reports so the students can see where the signals were in relation to our location.
The AmateurLogic.TV crew plan on attending and taping the event.
