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); 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 star tracker and maps.

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