General Thoughts / Observations

This flight was a test in both battery & flight duration. The balloon lasted longer than the battery with a total of 460 transmissions received over 46 hours. This flight saw plenty of long distance signals, reaching Hawaii, Rio de Janeiro, Morocco, Iceland, Denmark, and more!

My first WSPR flight where I received signals outside of APRS range. This flight had a smooth float and consistent signals.

Thoughts for next time

Increase sleep time to extend the battery life.
