      Add a BPSK decoder Script · 9d41d898
      Patrick Dohmen authored
      Add a BPSK decoder script for frames transmitted in AX.25, using G3RUH
      scrambling and without. Baudrate is set via parameter "baudrate", all
      filters, taps, offsets, etc are calculated using this parameter. Decoder
      tested with 1k2 bps and 9k6 bps.

      Remove .txt decoded frames files · 3cc611c6
      Manolis Surligas authored
      * 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 · d951fa92
      Manolis Surligas authored
      * 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

      Add AFSK1200 decoder · 53e0db48
      Manolis Surligas authored
      * 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

      change settings to parameters · 06436605
      Corey Shields authored
      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.

      Add support for passing manually various device parameters · f3de63ca
      Manolis Surligas authored
      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.

      waterfall fm_demod script · da4d89f2
      Corey Shields authored
      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.

      Improve the generic FM demodulator · ce8d54eb
      Manolis Surligas authored
      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
