This is a fork from Martinber's rtlsdr_sstv project. Most of the code and the most important decoding stuff was taken from Martin's project.
cd pd120_decoder/
source venv/bin/activate
pip install -r requirements.txt
./demod.py <path to wav file>This software is intended to be used (and integrated) with raspberry-noaa.
Some of the minor modifications I've done to Martin's work are about decoding existing ISS recordings from my weather station. Those modifications helps the software recognize multiple SSTV transmissions on a single audio file and to adjust the DC offset caused by doppler effect drift on frequency (as I'm not doing anything from RX side to fix that)
Decoding times for a 10 minute recording with two or three SSTV transmissions are around 2 minutes on my MacBook Pro 2019 and around 8 minutes on a Raspberry PI 4.
