Software
and Compatibility
One
of the V3’s greatest strengths is its extensive software
ecosystem. It works on:
-
Windows:
SDR#, HDSDR, SDR Console, CubicSDR
-
Linux:
GQRX, GNURadio, rtl_fm, rtl_tcp
-
macOS:
CubicSDR, GQRX
-
Mobile
(via OTG): SDR Touch (Android)
It
also supports specialized tools such as:
-
dump1090
for ADS-B aircraft tracking
-
rtl_ais
for AIS maritime signal decoding
-
SatDump
for weather satellites
-
Unitrunker
and DSD+ for trunked and digital voice reception
The
RTL-SDR V3 is a compact, USB-powered software-defined radio receiver
that gives users access to a wide range of the radio frequency
spectrum - from as low as 500 kHz up to 1.7 GHz. It is one of the
most widely used SDRs in the world, thanks to its excellent value
and versatility across many RF applications.
Encased
in a metal shielded enclosure with an SMA antenna connector, the V3
is designed for radio experimentation and monitoring.
