The images seem a bit scrambled, presumably due to missing data blocks. At that low a resolution, have you considered maybe Robot36 SSTV?

Images are all in order, but some have missing packets.
The problem with SSTV is the power required. From some looking it seems that transmitting would need at least 5 watts. This wouldn't be feasible running on the balloon, as it was powered by Energizer Ultimate Lithium batteries.
Oh, yeah FM transmitters can require a fair bit of power.
What is it using then, LoRA type stuff?
Yep, the radio link runs LoRa on the 33 cm band (915 MHz)
