Predictions

General Thoughts / Observations

This was a TR9 52” x 68” balloon, solar powered with six Aoshike cells. Once fully assembled, I tested the system - it transmitted and SDR sharp decoded the message.

It was pretty much a windless launch, I just let go and the balloon floated away - no drama. The only problem was that I never heard from it again, just another mystery.

Thoughts for next time

Keep the focus on building custom balloons for greater elevation.
