Manolis Surligas f3de63caf3 Add support for passing manually various device parameters
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.

Manolis Surligas cc9a305ebd Reduce RTL SDR buffers size
In memory limited devices like RPi, the default buffer allocation scheme
of the RTL driver causes problems to the async transfer engine.
This prevented the flowgraphs to start. 
Reducing the buffer size fixes this problem.

Corey Shields 6841dd5ae6 fix rtlsdr sample rate for rpi
1.5e6 is too high and causes timing clips in the raspberry pi. 1e6 was tested successully today and eliminates the clips.

Corey Shields 5603b47cd4 updated hw_settings.py
updated the hardware settings (gain/sample rate) based on testing with and for the new fm_demod script.

Corey Shields 7184f551a0 Change fm_demod to quadrature demod (#51)
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

Manolis Surligas ce8d54eb40 Improve the generic FM demodulator
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
