The DECT protocol is commonly used on modern digital cordless phones. This is a digital FM radio broadcasting signal that can be identified on a RF spectrum as the two solid blocks surrounding a standard wideband FM radio station.
The protocol is closed sourced, but the author of NRSC5 managed to reverse engineer it and create a decoder. A decoder for the blockstream project. This is a project that tries to beam down the bitcoin block chain from a satellite, with an RTL-SDR used as the receiver. See the related post for further information.
A simple program that aims to detect wireless bugs based on the strength of the signal emitted by the bug. Various decoders are written in GNU Radio and require it to be installed to run.
Redhawk is another digital signal processing package that is very similar to GNU Radio. It is designed to aid in the development, deployment, and management of real-time software radio applications. LabVIEW is a software package usually used for control systems engineering. WxToImg to a program which can be used to decode NOAA weather satellite data and then display and post process the weather images.
DSD is an acronym for digital speech decoder. For DSD you will need to copy cygwin. There is now also the in development DSD 1. SondeMonitor is commercial software with a 21 day free trial that is used to decode various weather balloon radiosonde telemetry signals. A modification of fldigi that can receive telemetry from amateur high altitude balloons HABs. Use in conjunction with a general purpose SDR receiver and pipe the audio output to dl-fldigi.
It contains a database of aircraft and will display their images if they exist. Use in conjunction with a general purpose SDR receiver and pipe the audio output to Acarsd.
ShipPlotter is a commercial program which can plot ship positions on a nautical map or Google maps from decoded AIS datastreams. It has a day free trial. Orbitron is a free satellite tracker. With a plugin, Orbitron can be made to control the tuned frequency in SDR allowing for automatic satellite tracking, and doppler effect correction.
Use in conjunction with the Orbitron SDR plugin. This mode is used by APRS radio hobbyists. This is a program designed to decode the Funcube satellite telemetry data. Use in conjunction with a general purpose SDR receiver and pipe the audio output to the dashboard. Another GPS decoder but compatible with Windows. See the related post for a tutorial on its operation.
Dstar is an DStar decoder program. Use in conjunction with a general purpose SDR receiver and pipe the audio output to dstar. A general purpose voice services system.
Is used to control a repeater tower. Spectrum Lab is a free specialized audio analyzer, filter, frequency converter, hum filter, data logger. It is usually used in the field of radio astronomy for things like meteor detection.
Baudline is a free audio spectrum analyzer usually used to analyze radio data signals. Use in conjunction with a general purpose SDR receiver and pipe the audio output to Baudline. HROFFT is a specialized audio analysis software program designed for monitoring meteor scatter signals.
Use in conjunction with a general purpose SDR receiver and pipe the audio output to Fldigi. MixW is a free software program used for decoding various digital ham radio signals. Sorcerer is a free software program capable of decoding a wide range of ham radio signals. Sorcerer is known for its decoder support for rarely used signals, but it is mostly used to decode STANAG signals.
Use in conjunction with a general purpose SDR receiver and pipe the audio output to Sorcerer. It is generally regarded as one of the best CW decoders available. Taxidecoder is a free mobile data terminal MDT decoder. It will only work in countries that use MDT data signals that taxi decoder supports. Use in conjunction with a general purpose SDR receiver and pipe the audio output to taxidecoder.
A PHP based web server program which can be used to record, log and analyze trunked radio traffic. Can be used to decode end of train, head of train and distributed power unit telemetry which is used on some trains.
Used for recording audio from an SDR with squelch feature that stops recording when there is no sound. Shows the current frequency and time wherever the mouse is.
A tool very useful for reverse engineering digital signals. Helps you extra the binary string and timing information. An upgrade to Inspectrum which gives it a GUI and more visual decoding features. Extremely useful for reverse engineering digital signals.
Not something you use via piping, but has can be useful for making timelapse waterfall recordings when a program does not have that feature by default. See the related post for more info. Also takes data from sigidwiki. A tool somewhat similar but a bit more advanced to Inspectrum for reverse engineering digital radio signals.
A decoder for ATCS signals that come from trains. Can be used to track train track status and positions of trains. Compatible with the signals used in the USA. Can also be used to decode the L-band Outernet signal. It seems that the server is Python based and the server runs on Linux.
If you decide to buy a dongle and try this out, note that scanning and producing a spectrum is slow. Same thing with the lower and upper frequency limits.
If you want anything much better than this you're going to have to spend about 1, bucks, so keep that in mind. I'll be sending the author 50 bucks, about what I wasted on Touchstone Pro, and I suggest you do the same. The world needs software like this. I like this app, I just wish it had the ability to set the range to sub-Mhz. For example I'd like to be able to scan An chance of this being possible? Toggle navigation. Rtl Sdr Software. Versatile, larger learning curve.
GPS location AX. General purpose multi-mode communications receiver, extensible, works on both GR 3. Popular, supports multiple DSP modalities, FFT algorithms, filter settings, Along with Linrad has the most configurable and flexible options, without building your own Gnuradio or adapting an existing flowgraph multimode, others. Will run on older hw. Tools to build your own receiver. Supports ppb,enhanced gain modes,runs well on older hw.
