SSTV on Raspberry Pi

Submitted by gerry on Thu, 06/16/2016 - 16:19

Following a suggestion by Galway VHF Group mamber Steve, EI5DD, I thought I would give SSTV a shot. It's not a mode I have any experience with, apart from hearing the transmissions at 14.230MHz when I tune around. Steve mentioned a cross-platform SSTV program QSSTV, which seems to run well on a Pi 2, so that's what I decided to use.


APRS

APRS is often misunderstood to mean Automatic Position Reporting System, when, according to creator Bob Bruninga, WB4APR, it actually stands for Automatic Packet Reporting System. Some might maintain that the primary purpose of APRS is vehicle tracking and service position reporting, and, while this is not entirely untrue, it does sell short the possibilities of this excellent technology.
