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.
In some cases (crash, inproper termination) a flowgraph failed to
produce a binary file that had exactly the proper number of float
numbers in order the gnuplot script to be able to convert it in a matrix
representation.
The updated script tries to truncate the binary file in such a way so it
can be converted into a matrix. This will allow waterfall images to be
created even after a crash.
System should have the "truncate" command line utility installed which
is part of GNU GNU coreutils.
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.

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
* UDP Message source can handle multiple data types
* Add a waterfall sink block
* Fix dependency issues with VOLK
* Add mean and max hold mode to the waterfall sink
* Add mean and max hold mode to the waterfall sink
* Install satnogs_waterfall.gp gnuplot script at
<install_prefix>/share/satnogs/scripts
* Automatically retrieve x and y axis ranges at the satnogs_waterfall.gp
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
The new transceiver has an FSK9600 receiver that supports legacy G3RUH
scrambled AX.25 frames.
However, due to some restrictions the transmitter is a custom structured
9600 FSK with a preamble of 8 bytes and 2-byte sync word.
