Developer R. X. Seger has recently released rx_tools which provides SDR independent ports for the popular command line RTL-SDR tools rtl_power, rtl_fm and rtl_sdr. This means that these tools can now be used on almost any SDR, such as the bladeRF, HackRF, SDRplay, Airspy and LimeSDR. If you don’t know what the tools do, then here is a quick break down:

rtl_fm / rx_fm: Allows you to decode and listen to FM/AM/SSB radio.
rtl_sdr / rx_sdr: Allows you to record raw samples for future processing.
rtl_power / rx_power: Allows you to do wideband scans over arbitrarily wide swaths of bandwidth by hopping over and recording signal power levels over multiple chunks of spectrum.

rx_tools is based on SoapySDR which is an SDR abstraction layer. If software is developed with SoapySDR, then the software can be more easily used with any SDR, assuming a Soapy plugin for that particular SDR is written. This stops the need for software to be re-written many times for different SDR’s as instead the plugin only needs to be written once.
