Then append these lines to /boot/config.txt : This will run all the decoding in one core using 5 signal phases instead of 10, which requires half of the CPU usage, while still being very accurate for MLAT.Īdditionally, we recommend to put these lines in /etc/rc.local :Įcho performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governorĮcho performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governorĮcho performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governorĮcho performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor Sudo /home/pi/airspy_adsb -l 30005:beast -x -m 12 If very high MLAT reliability is required, the following switche should be applied to the decoder: The following settings will force the “performance” governor at a much more acceptable CPU frequency for sustained operation without causing excessive heat and without sacrificing the performance of the decodes. The governor will keep swinging back and forth between these two extremes and the USB controller will drop whole packets, which could affect both the number of decodes and the MLAT timing. The CPU will start at a very high frequency (1200MHz), get very hot, then throttle back to a very low frequency (600 MHz). The latest Raspbian distros come with a new default CPU governor that is not suitable for sustained high performance operation. READ the instructions before doing anything. You need firmware version 1.0 rc7 or newer to use Airspy as an ADSB receiver. Using the ADSB decoder in embedded ARM boards

“`GLIBCXX_3.4.21′ not found” => Try installing GCC 5.

Sometimes using sudo makes things just magically work.

Try compiling the libairspy/libairspyhf from source.

The program runs, but cannot acquire the device: The user mode driver is probaby not up to date.Here’s a list of the most obvious ones people reported so far: What could go wrong in the Linux world? Well, many things ( see the GPL sections 15 and 16). Wget -qO - | sudo bash Linux Troubleshooting You can also use the automated installation script by Rodrigo Pérez which will do everything for you with a single command:

Running on x86 Linuxįirst, make sure you are have the latest version of libairspy installed.Įxtract “spyserver_linux_x86” and “nfig” from the standard zip, chmod and run. # For AirspyOne only – Useful for LNA’s and SpyVerterĮdit the configuration file if necessary and double click on spyserver.exe. # Set to -120000000 to enable the SpyVerter offset If the SpyVerter is used, the following parameters should be set in nfig: If you have many devices in the same server, you can have multiple configuration files and pass the right one as parameter to the executable. The SPY Server comes with a standard configuration file that allows you using Airspy or RTL-SDR directly without an upconverter. The bandwidth savings allows usage over the Internet, but still requires high speed connection. If the network bandwidth is not sufficient to handle the traffic, uncheck the “Full IQ” option and the server will only stream the FFT display data and reduced IQ data that it necessary for decoding one VFO. The “Full IQ” option allows streaming the entire spectrum from the device to the SDR client (SDR#). The default settings allow using the server in the LAN with optimal latency.

When there are more than one client connected, the center frequency of the device and the RF gain are locked.

When only one client is connected, full control (center frequency, gain) is granted. The SPY Server allows you to connect many SDR# “clients” to the same Airspy or RTL-SDR device over the network.

Since revision 1553, we offer a new utility for the Airspy series to convert a Raspberry Pi, an Odroid, or just your regular Windows or Linux PC into a fully featured SDR server. In any case, you should make sure the RF noise floor just overrides the quantization noise floor of the ADC, but no more.

Fine tune to maximize the SNR (the blue bar graph on the right).

If not, increase the gain by an extra notch.

Check that increasing the gain no longer increase SNR.

Increase the gain until the natural noise floor rises by about 5dB.

The following fine tuning procedure ensures you have the maximum SNR on the signal of interest while preserving the dynamic range: The “Linearity” mode is the one you want to start with: As depicted in this screen shot, there are many gain modes: Then next step is the gain configuration. Then run SDRSharp.exe and select the “AIRSPY” front-end:

Airspy was designed by the same people who developed the SDR# software so it’s the obvious choice for running Airspy and leverage all its powerful features.įirst, go to the download page and get a copy.
