November 28th Launch @ 10:05 AM – Launch location Springfield Township PA.
Today’s launch was perfect. We used 3 Chinese Mylar balloons with an APRS tracker a shown below. Jeff Elliott W3JVU was present to document with video showing the launch of the 20 grams solar powered tracker using only 7.3 grams of lift to each balloon covering the payload and 2 grams of free lift. As of this day at 14:51 hours the balloon is now coasting out above the Atlantic at a hovering altitude of 31,000 feet as depicted below. Additionally I have included a video link to the launch.
This was a previous launch using a W3UAV Tracker Assembly.
(This was an APRS only tracker that was launched using Hydrogen & 2 Mylar Balloons.
The Launch was using SSID W3UAV-15 at 9AM September 4th from Springfield Township.
Weather was cloudy but when we reached 5000 feet above the clouds the tracker became alert. As you can see below this tracker made it all the way to NY not far from Connecticut. The tracker used for this launch was from the recovered launch of the that made it to Delaware so I save having to spend another $100.00 for another tracker.

May 22, 2021 Launch of W3UAV-15 @ 10:30 AM
For those who are interested we launched W3UAV-15 using a Mylar Balloon with an APRS Tracker. The launch occurred from Tony McMonagle’s house in Springfield Township in the presence of Rick Goodman WA3USG and Jeff Elliott W3JVU. The balloon was filled with 5 grams of lift just a little more than recommended for the size of the balloon and payload. Just as expected we made it up to 23,120 feet. As you can see below the last position recorded was over the Chesapeake Bay before the balloon burst. We believe this occurred because we had too much lift and used helium which contained 80% helium and 20% air.
