	The frequency of AIS signal is 161.975 MHz and 162.025 MHz, and have the max range of about 70 km. Is is a line of sight signal. I wish to have 180 degrees view.

			* <code>/usr/local/bin/AIS-catcher</code>. Some parameters:
			** [-d:x - select device based on index (default: 0)]
			** [-gr RTLSDRs: TUNER [auto/0.0-50.0] RTLAGC [on/off] BIASTEE [on/off] ]
			** [-a xxx - set tuner bandwidth in Hz (default: off)]
			** [-N [optional: port][optional settings] - start http server at port, see README for details]
			* To share your raw feed with other AIS-catcher users (and see their data in your webviewer - see below) use -X. Additionally, for sending the messages via UDP to ports 10110 and 10111, we can use the following command:
			<code>AIS-catcher -v 10 -X -u 127.0.0.1 10110 -u 127.0.0.1 10111</code>
			* The AIS NMEA lines on screen can be suppressed with the option <code>-q</code>.
			* For RTL-SDR devices performance can be sensitive to the device settings. In general, a good starting point is the following:
			<code>AIS-catcher -gr RTLAGC on TUNER auto -a 192K</code>
			* to create a webviewer that you can access from your local network, use the following command:
			<code>AIS-catcher -N 8100</code>
