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 toContinue reading “Pico Balloon SSTV on 20 m – First Light”

SSTV Tethered Balloon – Sunday, March 6 @ 11:00AM @ Berkeley Marina

We’re trying something new this time: floating a tethered balloon with an ESP32-CAM that will transmit SSTV images on 20m, frequency 14.236MHz USB Mode Martin-1. This is a project that Kazu AG6NS has been working on recently, with some help from Martin W6MRR. To see this in person, go to the northern area of theContinue reading “SSTV Tethered Balloon – Sunday, March 6 @ 11:00AM @ Berkeley Marina”
