General Thoughts / Observations
This is my second WSPR flight, MM28 failed presumably because I used quarter wave antennas. This flight was to test the WSPR setup with a half wave transmitting antenna and it worked, I had success in receiving WSPR signals. After climbing and transmitting for 2 hours and 45 minutes, the balloon was not heard from again.
The WSPR aspects worked fine, why the signals stopped being heard is unknown.
