Are there any command line tools for rtl-sdr?
librtlsdr provides quite a few useful command-line tools for RTL-SDR dongles (including rtl_fm, rtl_sdr, and rtl_power). rx_tools is derived from these popular tools, but adds support for other more powerful SDR hardware, including the bladeRF and HackRF, thanks to the SoapySDR abstraction layer.
What’s the frequency deviation of a SDR receiver?
The SDR# receiver is tuned to 145.050 MHz and the bandwidth set to 20 kHz. The deviation level of the 1200 Hz tone is increased until a null appeared on the carrier frequency.
Which is the GSM frequency calibration tool for rtl-sdr?
As I covered in SDR calibration via GSM FCCH using Kalibrate and LTE-Cell-Scanner on RTL-SDR and HackRF, the “kalibrate” GSM frequency calibration tool has at least four separate forks: kalibrate for USRP, kalibrate-rtl, kalibrate-hackrf, and kalibrate-bladeRF — one for each SDR.
Is it possible to write radio software with SDR?
The great promise of SDR is “it’s just software” — with sufficiently capable hardware, you can write radio software to do practically anything. However, not all software is made equal. SDR applications must interface with the hardware by some mechanism.
How to install rtl-sdr drivers in Notepad?
Run the install-rtlsdr.bat file to download the RTL-SDR drivers. In the SDR# folder find the file spyserver.config. Right click it and select ‘Open With -> Notepad’.
How does a spyserver work with a rtl-sdr?
Running a SpyServer allows you to connect to and use a remotely positioned RTL-SDR over a network connection (such as a local LAN/WiFi or the Internet). Once connected, using the dongle is the same as if the dongle was directly connected to the users PC. An example SpyServer Overview (Can use an RTL-SDR instead of the Airspy HF+)
What to do if RTL-sdr.bat fails to download DLL?
If install-rtlsdr.bat fails to download the dll or zadig, do a manual driver installation. If Zadig is smaller than 5000kB (5MB), the download has failed and you should download Zadig manually. Plug in your dongle.
