A binary device for transmitting 'slow images' on variable frequencies between 88-108 Mhz. It runs on a raspberry pi + pi camera which takes in an interval of 1:57 min a photo, saves the phota and modulates the photo in SSTV (Slow Scan Television) sound format and transmits the sound file via a Pi-box - micro FM and streaming unit. The antenna connected is a dipole calculated in relation to the frequency you want to transmit.


Inspired and with tools/scripts of:

For receiving and demodulating the images a binary device is needed + an installation of Qsstv (laptop, Linux) or Robo36 ( smartphone, Android).
