rxseger / rx_tools

rx_fm, rx_power, and rx_sdr tools for receiving data from SDRs, based on rtl_fm, rtl_power, and rtl_sdr from librtlsdr, but using the SoapySDR vendor-neutral SDR support library instead, intended to support a wider range of devices than RTL-SDR

Done.

CubicSDR and rtlsdr device working so i don't think it's SoapySDR

@rxseger You might want to add some %s, SoapySDRDevice_lastError() to some of the error messages. My guess here is that the complex int16 format is not supported. But that error message is not getting shown.

@starvald Can you try SoapyAirspy? Its not 100% complete, but it should implement complex int16. The devices from the SoapyOsmo wrapper only do floats. You will have to uninstall SoapyOsmo to avoid a name conflict though.

Thanks, using SoapyAirspy the device is now used but i have a few other problems the audio plays very slowly.

rx_fm -f 99.3M -M fm -s 170k -A fast -r 32k -l 0 -E deemp -w 2500000 -g LNA=11,MIX=5,IF=8| play -r 300k -t raw -e s -b 16 -c 1 -V1 -

using play -r 300k it's playing at the right kind of speed. if i don't use -w 2500000 is plays the wrong station 97.4MHz rather than 99.3MHz, i think the offset tuning is a bit off.
