      Connect waterfall sink in front of filter · 0064bc83
      Patrick Dohmen authored
      Connecting the waterfall sink behind the FFT Filter causes the
      waterfall to show only the filtered APT signal. Fixing this needs
      an additional resampler.

      Fix NOAA APT waterfall bandwidth · e831d815
      Patrick Dohmen authored
      The flowgraph for decoding NOAA APT images generates a waterfall with a
      bandwidth depending on the default samplerate of the SDR hardware.
      USRPB200 defaults to 500 ksps, which produces an output of 125 ksps
      after the "first_stage_decimation" which is fixed to a value of 4.
      Changing the hardware to an "rtlsdr" also changes the default
      samplerate to 1 Msps which results in a waterfall bandwidth of 250 kHz
      (+- 125 kHz). Connecting the waterfall sink behind the FFT Filter,
      which has a decimation set to match an output samplerate of 125 kHz,
      seems to be correct! This produces waterfalls with a bandwidth of
      125 kHz (+- 62,5 kHz).
      
      Fixes issue #128

      Tune CW parameters · 6b1e3d38
      Manolis Surligas authored
      * Set the loop bandwith of the PLL to a lower value, to get rid off the
      DC leakage and improve SNR
      * Set the AGC update rate to a higher value
      * Decrease the CW decoding threshold

      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.

      Fix METEOR flowgraph · 22cb5e18
      Manolis Surligas authored
      * Set the METEOR flowgraph in non-X mode
      * Reduce the stored bandwidth by a factor of 2. Captures have shown that
      twice the bandwidth of the METEOR is enough for RRC and clock recovery

      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

      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.
