We flew a 3,000 gram balloon filled with almost 200 cubic feet of hydrogen. The plan was to reach 126,000 feet but we only made it to 119,323 feet.
The balloon flew a primary VHF APRS beacon with a twinlead dipole antenna. The payload landed on the VHF antenna and couldn't be heard. The LORA beacon continued operating and lead us to the payload.
I recorded the LORA beacon with my home base station and received most all of the packets until the end. I also copied from my car with a mag mount. All communications stayed above -90 RSSI and the system is supposed to operate down to -120. The beacon antenna was just a 6.5" piece of wire.
