NanoSDR is a ready to use distribution for NVIDIA Jetson Nano 2G and 4G dedicated to amateur radio applications. It is based on a Ubuntu 18.04 root filesystem and LXDE desktop and comes with several popular apps compiled for the Nano (see details below).
SDR-Technologies develops different SDR products based on NVIDIA embedded GPU and we have worked on this distribution to estimate the processing capabilities of these "small" processors. Originally for internal use, the team (mainly licensed amateurs) believes this could be something useful for the community and we have decided to release the work as a set of "ready to use" SD-Cards.
The images are quite big and are hosted in a public web server, please bear in mind you are about to download several gigabytes of data before being able to play with it...
The files are provided "as is" and we cannot commit to release regular updates, but we will continue to improve it and maybe offer here scripts to update/add new features to the existing image.
Feel free to use the "Github issues" features to suggest improvements.
Download image corresponding to your Jetson-Nano.
Take care to use adequate image since hardware is not the same for Nano-2GB and nano 4GB models.

Default user is ubuntu , default password : ubuntu
First boot is longer than usual since the Nano needs to recreate SSH keys, and expand filesystem partition to maximum available size.
Once session is opened feel free to change locale settings and keyboard mapping.
Pre-installed languages/keyboards : english-US, french, german, spanish.
Most of installed applications are supporting SoapySDR.
However only RTLSDR and PlutoSDR support have been deeply tested.
Feel free to install SoapySDR module corresponding to your device if not yet installed.
- Gcc 7 and 8
- Cuda Toolkit version 10.2
- Boost, Volk, ....
- Git , CMake, Qt 5
Current version installed on NanoSDR is v0.8
Supported modules are : BladeRF, plutoSDR, RTLSDR, SDRPlay, Airspy, SoapyRemote

This version was installed and compiled using PPA sources, gr-iio module (PlutoSDR support) is also installed.
- built-in source types:
gr-osmosdr f9a99388 (0.1.5git) gnuradio 3.8.2.0
built-in source types: file osmosdr rtl rtl_tcp uhd plutosdr miri hackrf bladerf rfspace airspy soapy redpitaya spyserver
Specific compilation with plutoSDR and Spyserver client
https://github.com/dk2ro/gr-osmosdr-pluto-spyserver
Please note that osmocom is not really maintained with plutoSDR support, hopefully some forks are working well.
This is the latest version compiled from sources : https://github.com/csete/gqrx
Note : Spyserver client might crash GQRX if incorrect samplerate is set. Should work better on a LAN than using internet-spyservers because he needs a stable stream.

SigDigger is a free-as-in-freedom digital signal analyzer with an intuitive GUI that provides different capture modes (replay and real-time capture from the different SDR devices supported by SoapySDR), analysis modes (burst and streaming), signal characterization (Doppler shift, time and frequency measurements, manual and automatic parameter estimation) and fully configurable demodulators for analog audio (AM, FM and SSB), video (PAL, NTSC and custom modes) and digital modes (PSK, FSK and ASK).

QSSTV has been installed from Ubuntu repository, since sources are not available.
Compiled from sources available here: https://physics.princeton.edu/pulsar/k1jt/wsjtx-2.2.2.tgz
LuaRadio can be used to rapidly prototype software radio applications, modulation/demodulation utilities, and signal processing experiments. It can also be embedded into existing radio applications to serve as a user scriptable engine for signal processing. LuaRadio is very similar to GNUradio using blocks, sources, sinks, except it use scripts (no GUI).
Very nice and functional examples are provided on the website &github for RTLSDR device, can be easily adapted to other devices. Website : https://luaradio.io
https://github.com/szpajder/RTLSDR-Airband/
Compiled with following specific options : PLATFORM= armv8-generic make NFM=1 PULSE=1 WITH_RTLSDR=1 WITH_SOAPYSDR=1
Default configuration file is : /usr/local/etc/rtl_airband.conf
To use your own configuration file use -c parameter followed by full path to your customized config file.

This is a full version of FFMPEG including all available supported formats.
Please report to the author's repository for GPU-accelerated decoders/encoders use.
Since it relies on GPU hardware for acceleration, you have to run it as sudo user.

For PlutoSDR run : rtl_433 -d plutosdr ....
https://github.com/rxseger/rx_tools
Tool for transmitting data to SDRs, based on rtl_sdr from librtlsdr, and rx_sdr from rx_tools, using the SoapySDR vendor-neutral SDR support library, intended to support a wide range of TX-capable devices.
https://github.com/triq-org/tx_tools
This tool has not been tested due to lack of time ...

Note : original executable "dump1090" as been renamed by the author. Use readsb command instead.
For plutoSDR use : dump1090 --device-type plutosdr
Conda installer for arm64 platforms comes from conda-forge : https://github.com/conda-forge/miniforge/releases/download/4.9.2-3/Miniforge-pypy3-Linux-aarch64.sh On the jetson nano, installation path is located in /opt directory.
First, thanks to the authors of those nice SDR applications !
Thank you for giving your time testing the nanoSDR image and providing suggestions and ideas:
