KD2EAT: “Tracking and Repurposing NWS Radiosondes for High Altitude Balloon Tracking” at New England Sci-Tech ARS Meeting, December 21, 2021

New England Sci Tech logoThe New England Sci-Tech Amateur Radio Society (NEST) will meet on-line and in-person on December 21, 2021 at 7 PM and feature Mike Hojnowski, KD2EAT,  who will present on “Tracking and Repurposing NWS Radiosondes for High Altitude Balloon Tracking.”
Mike is an Amateur Extra operator, licensed since 2013. He’s the club advisor for the Amateur Radio Club at Cornell University (W2CXM) and is very interested in High Altitude Balloons and tracking. He has launched dozens of HABs and Pico flights, one of which is circumnavigating the planet. He’s designed, built and coded APRS and WSPR trackers using Surface Mount technology. Mike has a receiving station for National Weather Service Radiosondes and enjoys tracking and recovering them. NWS Buffalo just switched to “RS-41” sondes, which can be reprogrammed to beacon APRS, 4FSK and several other protocols. Mike is collecting some that land in his area to repurpose for HAB tracking so that he can give them to other balloon enthusiasts. His presentation will be about the software he’s using to track and recover the NWS radiosondes, and how to go about reprogramming them. In his spare time, Mike reluctantly does his day job, and sleeps.
Come meet at NEST! We usually have pizza! (Face masks still required, please.)
5:00-7:00: radio room open; informal radio activities.
