		+	===Troubleshooting===

		+	Sometimes some more configuration steps are needed to use an Airspy device. If when you run <code>SoapySDRUtil --probe=“driver=airspy”</code> you get a "missing id" error you probably need the following :
		+
		+	First a configuration file that will block the kernel driver from loading:
		+
		+	<code>/etc/modprobe.d/airspy-blacklist.conf</code>
		+
		+	<code># Block AirSpy kernel module from loading</code>
		+	<code>blacklist airspy</code>
		+
		+	Second a configuration file that will recognize the device when inserted.
		+
		+	<code>/etc/udev/rules.d/52-airspy.rules</code>
		+
		+	<code>ATTR{idVendor}=="1d50", ATTR{idProduct}=="60a1", SYMLINK+="airspy-%k", MODE="660", GROUP="plugdev"</code>
		+
		+	Make sure the satnogs user is member or the group <code>plugdev</code>. You can check running this command <code>sudo -H -u satnogs id</code>
		+
		+	If you need to add it to the <code>plugdev</code> group, run this command <code>sudo usermod -a -G plugdev satnogs</code>
		+
		+	Finish with a reboot

	For reference see also the Airspy driver library linearity gain settings in [https://github.com/airspy/airspyone_host/blob/bceca18f9e3a5f89cff78c4d949c71771d92dfd3/libairspy/src/airspy.c#L117-L122 libairspy/src/airspy.c#L117-L122].		For reference see also the Airspy driver library linearity gain settings in [https://github.com/airspy/airspyone_host/blob/bceca18f9e3a5f89cff78c4d949c71771d92dfd3/libairspy/src/airspy.c#L117-L122 libairspy/src/airspy.c#L117-L122].
		+
		+	The airspy driver offers "Linearity" and "Sensitivity" gain settings, using a look-up table to configure all three gain stages from a single value (optimized for linearity and gain respectively). Those modes are unfortunately not available through the SoapyAirspy module (see [https://github.com/pothosware/SoapyAirspy/pull/14 SoapyAirspy#14]).
		+
		+	The "Overall" gain mode is a soapy-specific driver-independent mode to configure all gain stages based on the single gain value from <code>SATNOGS_RF_GAIN</code>. It tries to evenly distribute the gain, potentially resulting in non-optimal configuration. Thus for achieving optimal results the "Settings Field" mode is recommended, where all three gain stages can be configured separately.
