Using OpenWebRX with an AirSpy

1. You should start by installing the airspy_rx tool on Linux:

   sudo apt-get install build-essential cmake libusb-1.0-0-dev pkg-config git clone https://github.com/airspy/host airspy-host cd airspy-host mkdir build cd build cmake .. make sudo make install sudo ldconfig

2. You should make the follwoing changes to config_webrx.py:

   samp_rate = 2500000 center_freq = 144900000 start_rtl_command="airspy_rx -f144.9 -r /dev/stdout -a1 | nc -vvl 127.0.0.1 8888".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate, ppm=ppm) format_conversion="csdr convert_i16_f"

Please make sure that the center frequency after the -f switch refers to the same (in MHz) as the center_freq parameter (in Hz).

If you want the 10 Msps sample rate, you should set the -a0 switch on airspy_rx, and set samp_rate=10000000.
