* Decoded frames are stored only in hex files
* Output only the CRC valid frames. For now, in order to get the CRC
failed manual edit of the flowgraph is needed. In the near future, a
command line arguemnt will enable/disable
* Fix clock recovery issue on AFSK 1200 decoder
* Improve performance of AFSK 1200
* Make AFSK 1200 decoder to produce waterfall and audio file with the
same characteristics as the generic FM demodulator flowgraph for a
unified output experience in the SatNOGS network
* AFSK1200 decoder with AX.25 frame support
* Fix issue with the AX.25 decoder when the frame has only one AX.25
SYNC flag
* Fix clear text debug output to print each one of the characters and
not the string, so that the payload can be partially be printed even if
it contains non-printable characters
* Add AFSK1200 decoder example that can decode frames from an .ogg file
retrieved by the satnogs-network
This change sets all of the expected parameters to the g3ruh script. Without it, satnogsclient will send it paremeters that it does not understand, causing it to exit out.
All flowgraphs now support user defined parameters for most of their
configuration capabilities. These include:
* RF gain
* IF gain
* BB gain
* Custom device arguments for setups with multiple SDRs. These
coresponds to the 'Device arguments' field of the Osmocom source block.
* Antenna selection for devices with multiple antennas (USRPs, etc)
Changing sampling rate is not supported (yet).
For listing the arguments just execute <flowgraph> --help in a terminal
window.
Adds a script to demodulate SSB (more specifically for BPSK where we can count on a fixed frequency vs linears).
Also adds the apt script to CMakeLists.txt for satnogs/gr-satnogs#81
fm_demod script that also writes waterfall data (credit to surligas, I'm just committing)
Also FFT needs to be added to CMakeLists.txt to build in some conditions.
see also satnogs/gr-satnogs#42
Taking out WBFM/NBFM for a straight quadrature demod method
Change from 44.1k output to 44k output to be more compatible
with gr-satellites
Also changing rtlsdr to a 2msps rate by default
The FM demodulator now supports a variaty of hardware setups and saves
the WAV file for further processing. A set of command line arguments can
control most of the flowgraph internals, such as the wav file name and
storage path e.t.c.
TODO: Check the settings for all the available hardware
