SSTV (Slow Scan TeleVision) is a picture transmission method that converts images into a sound signal. Right now, I have built only a rudimentary encoder using MATLAB. I will improve the same and put up a decoder code when I manage to build one. ...
Encoder managementYou can use sstv_create_encoder() and sstv_delete_encoder() to request and return an encoder context to the library.sstv_image_t image; ... set up image ... const size_t SAMPLE_RATE = 48000 void *ctx; if (sstv_create_encoder(&ctx, image, SSTV_MODE_FAX480, SAMPLE...

Andrew was able to receive several SSTV images using an R820T dongle tuned to the 27 MHz (11 meter) band. He also used a Funcube Dongle+ and got similar results. Check outhis postfor some of the images he received, and his video below for an example of the receiving process. ...
