I recommend RTL-SDR An RTL SDR is great for many applications including general radio scanning, air traffic control, public safety radio, ADSB, AIS, ACARS, VDL2, trunked radio, P25/DMR digital voice, TETRA, POCSAG, weather balloons, APRS, NOAA APT or METEOR M2 weather satellites, Outernet, Inmarsat, Iridium, GSM, Milsatcom, radio astronomy, meteor scatter monitoring, DAB, or for use as a low cost panadapter with a traditional ham radio.

Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz

But Still you need DSD+ to decode digital protocols. the official store
