Pico Balloon SSTV on 20 m – First Light

Last Sunday Kazu AG6NS and I tried putting up a tethered pico balloon up flying Kazu’s SSTV code on a ESP-32. It was sending “Martin-1” mode SSTV directly modulating a Si5351 clock generator chip. Due to slow but steady light winds it spent most of the time flying horizontally. We will have something ready to fly soon – stay tuned!
