Description

From the listing uploaded by “appupdater”.

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