N6NFB-1 Flight Results
Unfortunately, the tracker electronics did not power up on launch day, November 11th. We thought all was lost, but it awoke the next day in Maidenhead grid square DL58, which is ~1640 km (~885 mi) southeast of the launch location. The balloon was at an altitude between 9,900 and 11,100 meters (~32.4k to ~36.4k feet). Only 11 WSPR packets were received by the network on the second day.
In total, only 29 packets from this picoballoon were received by the WSPR network, indicating that something was wrong with the transmitter or antenna. This balloon transmitted for 3 days total.
The last packet received from this picoballoon on November 14th was in EL77, which is about 260 km (~160 mi) west of Tampa, Florida. This final day the balloon was floating around 9,900 meters (~32.4k feet) altitude.
