Initially, it started transmitting only one SSDV image #224 (It even transmitted an image stored on board. @sv2hwm received this image and posted it HERE).
Just a few minutes ago HADES-SA crossed the skies over Brazil transmitting the images #214, #215, #216, #217, and #218.
Unfortunately, my reception isn’t great, and it seems the satellite is rotating slightly. Below are my results:
Once you demodulate, 2 files will be generated… The TLM files and the BIN files (Use the BIN files to generate the images and generate the audio CODEC2)
To generate SSDV, use SpinnyONE SSDV utilities… It’s super self-explanatory, just read the readme_ssdv)
To summarize:
Take the files sat_03_type_10_ssdv_img_XXX_packet_XXXX.bin generated by KISSGENESIS and copy them to the root folder of SSDV utilities
Open the command prompt in the root folder of SSDV utilities and run the command ./run_ssdv.bat xxx (Replace xxx with the ID of the image you received)
Congratulations, you have an SSDV image of this beautiful bird
For CODEC2, the process is basically the same. The difference is that you only need to run the run_codec2.bat file from CODEC2 utilities (no action is required via CMD).
Ahh obviously this is the process for Windows machines
… whoops! Just noticed there were a small number of files in this downlink for image #'s 221, 222, & 223 as well. Of course you don’t get much w/ only a couple of frames.
… and a VERY important reminder. Demodulating a USB signal is always tricky because you have to be much more ‘centered’ on the signal than if it was FM. To help with that, SoundModem has a wonderful setting that creates additional decoder pairs to the left & right of dead center - you will often get a LOT more decodes than if you were only decoding a single pair of freqs on the audio spectrum. Here is Andy’s how-to on that:
everyone should do this advice. thank you! and can you ask him, i try tx and record the audio using this soundmodem for hades-sa, and try to replay the recording, but it refuse to decode. is it possible to use this modem to decode for non hades ? thank you!
transmitting the images #214, #215, #216, #217, and #218.
