Slow Balloon to China using APRS and ISS

Amateur Radio enthusiasts have stepped up their game in Katy, TX. The South Texas Balloon Launch Team will launch a balloon at 1500 CST (2100 UTC) on Saturday, February 11th. The primary goal of the launch is to send an amateur radio balloon across the Atlantic and Mediterranean to Nanjing, China, the final estimated destination. A unique feature of the balloon is the frequency agile APRS transmitter that will change frequency according to where it is geographically located. The call sign to be used for APRS is KT5TK-11. It will also use the orbiting International Space Station as a relay to reach ground stations thousands of miles away. This will allow anyone to view the balloon’s progress as well as speed, altitude and direction.

This will be interesting to watch as it travels half way around the world.

**14 Feb 2012 Update**

Andy, W5ACM stated the most likely cause for the loss of reporting was due to frozen batteries or electronics. He has posted pictures and videos of the BLT-28 launch on his site.
