Marty Wittrock has done a lot of previous work figuring out how to TX with LimeSDR and SDRAngel. One good feature is that if you have a TX capable SDR like a HackRF, PlutoSDR, BladeRF or LimeSDR then SDRAngel can also be used for TXing. However, SDRAngel has certain features that make it a good program to have in your SDR software arsenal. It is compatible with Windows and Linux systems. SDRAngel is a general purpose SDR program similar to other programs like SDR#, HDSDR and SDR-Console. We note that the video doesn't show the following additional features such as an analog TV decoder, the SDRAngel "ChirpChat" text mode, a FreeDV decoder and several other features. Beacons: Monitor propagation via amateur radio beacons, and plot them on a map.Digital voice handled by the built in DSD demodulator, and includes DMR, dPMR and D-Star. QSO Digital and Analog Voice: Decode digital and analog voice.Channel Analyzer: Analyze signals in the frequency and time domains.APRS/AX.25 Satellite: Decode APRS messages from the ISS and NO-84 satellites, via the built in decoder and satellite tracker.APRS: Decode APRS data, and plot APRS locations and moving APRS enabled vehicles on a map with speed plot.Radio Clocks: Receive and decode accurate time from radio clocks such as MSF, DCF77, TDF and WWVB.Graves Radar Tracker: For Europeans, track a satellite and watch for reflections in the spectrum from the French Graves space radar.Airband Voice: Receive multiple Airband channels simultaneously.Noise Figure Measurements: Together with a noise source you can measure the noise figure of a SDR.Radio Astronomy Solar Observations: Similar to the Hydrogen line app, allows you to make solar measurements.Radio Astronomy Hydrogen Line: With an appropriate radio telescope connected to the SDR, integrates and displays the Hydrogen Line FFT with various settings, and a map of the galaxy showing where your dish is pointing.DAB+: Decodes and plays DAB digital audio signals.VOR: Decodes VOR aircraft navigational beacons, and plots bearing lines on a map, allowing you to determine your receivers position.AIS: Decodes marine AIS data and plots vessel positions on a map.DVB-S: Decodes and plays Digital TV DVB-S and DVB-S2 video.NOAA APT Decoder: Decodes NOAA weather satellite images (in black and white only).ADS-B Decoder: Decodes aircraft ADS-B data and plots aircraft positions on a map.From the video we can see that SDRAngel now comes stock with a whole host of built in decoders and apps for various radio applications making it close to an all-in-one SDR platform. Thanks to Jon for writing in and sharing with us a demonstration video that the SDRAngel team have released on their YouTube channel. We've posted about it several times before on the blog, however we did not realize how much progress has occurred with developing various built in plugins and decoders for it. SDRAngel is a general purpose software defined radio program that is compatible with most SDRs including the RTL-SDR. It’s a straight port of the desktop application, so although it will run on a phone, probably best used on a large tablet with a stylus or mouse. Satellite tracker, star tracker, maps and rotator controller.2D and 3D signal analysis in both time and frequency domain with statistical measurements of SNR, THD, THD+N, SINAD, SFDR and channel power.RTL SDR, Airspy, Airspy HF, LimeSDR, HackRF and SDRplay support via USB OTG as well as networked SDRs.AM, FM, SSB, Broadcast FM and DAB, AIS, ADS-B, Digital Voice (DMR, dPMR, D-Star, FreeDV), Video (DVB-S, DVB-S2, NTSC, PAL), VOR, LoRa, M17, Packet (AX.25), Pager (POCSAG), Radiosonde (RS41), Time signal (MSF, DCF77, TDF and WWVB) modems.It includes most of the functionality of the desktop version of SDRangel, including: This is an amazing development that could open up many doors into portable decoding setups as the Android version supports almost every decoder implemented on the desktop version. Thank you to reader Jon for writing in and noting that SDRangel has recently been released for Android as a free Google Play download. SDRAngel is set apart from other programs because of it's huge swath of built in demodulators and decoders. SDRangel is a free open source software defined radio program that is compatible with many SDRs, including RTL-SDRs. SDRangel Now Available on Android: Mobile ADS-B, AIS, APT, Digital Voice, POCSAG, APRS, RS41 Radiosonde Decoders ExtIO with Decimation & Tuner Bandwidth Controls.Manual gain controls and decimation driver.Measuring Traffic Volumes with Passive Radar.SignalsEverywhere Direction Finding Tutorial.Measuring Filter Characteristics & VSWR.Performing Replay Attacks with RTL-SDR and RpiTX.QRP (FT8, JT9, WSPR etc) Monitoring Station.Decoding 433 MHz ISM Band Weather Stations.GOES 16/17 and GK-2A Weather Satellite Tutorial.
