That broadcast on the 433.92MHz frequency. This Application using Airspy SDR or RTL2832 based DVB dongle, can decode some signals from some temperature sensors (home weather stations), remote control keys, and others. MeasurementsGitHub - netdoggy/rtl_433_airspy: Airspy port of rtl_433. The expected pricing of the HF+ preselector is US$49, and it will be ready for sale in a few weeks. Output is send in the form of NMEA messages to either screen or broadcasted over UDP.The Airspy HF+ preselector needs to be soldered directly onto the HF+'s PCB, and once installed it automatically switches bands using GPIO expansion ports controlled automatically via tuning in SDR#, so no external switching is required. This package will add the AIS-catcher command - a dual channel AIS receiver for RTL-SDR dongles, Airspy Mini, Airspy R2, Airspy HF+, HackRF, SDRplay (RSP1, RSP1A and RSPDX for now), SoapySDR, input from file and over ZMQ and (RTL) TCP.
AIS-catcher - A multi-platform AIS receiver. See supported devices for a complete list.Use rtl-sdr as a high quality entropy source for random number generation. Gqrx supports many of the SDR hardware available, including Airspy, Funcube Dongles, rtl-sdr, HackRF and USRP devices.
RASPBERRY AUDIO SPY SOFTWARE
Gqrx is an open source software defined radio receiver (SDR) powered by the GNU Radio and the Qt graphical toolkit.
RASPBERRY AUDIO SPY WINDOWS
SPY Server - SDR Server for Windows Airspy R0, R2, Mini, Airspy HF+ and RTL-SDR can be used as a high performance SDR receiver capable of streaming separate chunks of the spectrum to multiple clients over the LAN or the Internet. B) Other set of tracking gear (west side of house): RPI4 + Airspy mini + RTL-SDR-ADSB-LNA. A) One set of tracking gear (middle of roof): OdroidC2 + RTL-SDR + RTL-SDR-ADSB-LNA. It is interesting that the Airspy is pulling in 50% more messages than the RTL-SDR dongle yet both have roughly the same number of planes in track.
Compared to dedicated commercial ADS-B receivers which can go for between $200 - $1000, the $20 RTL-SDR is very attractive for the hobbyist in terms of price.
