About this app

SDRangel is the software frontend of a SDR (Software Defined Radio). When used with SDR hardware via USB OTG, it can be used to transmit and receive radio signals.

Modems are included for a variety of standards, including: ADS-B, VOR and ILS (aircraft); AIS and Navtex (marine); APT (NOAA weather satellites); AM, FM, SSB, M17, Packet / AX.25 / APRS, FT8 and RTTY (ham radio); Broadcast FM and DAB (broadcast radio); DMR, dPMR, D-Star and YSF (digital voice); NTSC, PAL, DVB-S and DVB-S2 (video); End-of-train; POCSAG (pager); MSF, DCF77, TDF and WWVB (radio clocks) and RS41 (radiosondes). Signals can be visualised in the frequency and time domain in 2D and 3D.

SDRangel also includes an integrated satellite tracker, Morse decoder, star tracker and maps.

SDRs supported include RTL SDR, Airspy, Lime, HackRF and SDRplay.

SDRangel was designed as a desktop application, and so will work best on tablets with large screens and a mouse or stylus.

Ratings and reviews

It is close, but could use an update. It does not seem to have modern Android permissions supported for actually writing files, so the file sink doesn't work and I can't record to any location. Though I see updates in the change log related to Android, it does not appear those updates are making it to the Play Store.

SDRangel is in my opinion pretty much the best RTL-SDR software it's very versatile with so many modules it can basically replace most other rtl-sdr software as it can do almost everything you need, on PC it's awesome but the mobile version is exactly the same as the PC version so it is very crowded on a mobile device screen with all the buttons and controls being tiny and tricky to use, probably a lot better on a tablet screen but not so user friendly on a phone screen, but worth having.

Getting 5 stars straight off the bat for even getting this ported to Android. There are some bugs, which I more than expected. The main ones I've hit are trying to use more than 1K FFT and adding an Audio output source making my own Workspace. I suspect this was because of only having 3GB RAM, will play again later on my 12GB Sammy 😁
