Testing SSTV Transmission with the HackRF and Portapack

Last week we made a post about the HackRF Portapack, and gave some examples of it in action. Recently the furtek Havoc firmware for the portapack was updated, and it now supports SSTV transmission. Over on Twitter, Giorgio Campiotti‏ @giorgiofox has uploaded a video showing an example transmission in action.

In the video the HackRF with Portapack transmits a test SSTV image to an Elecraft K3 ham radio, which is linked to a PC. SSTV decoding software on the PC turns the data back into an image.

SSTV stands for ‘Slow Scan TV’, and is a method used by hams to send images over radio. Typically this activity occurs on HF frequencies. Sometimes the ISS transmits SSTV images down to earth as well to commemorate special events.
