BladeRF xa4, running with a LNA/power amp. Setup on the 2m/70cm bands to assess local radio data. This SDR is the best choice on the market for pros, the FPGA is large enough for most common DSP and standalone demodulators you would need. The ADC gives a nice 12bit resolution and 2x2 MIMO for multi-path propagation. Thanks to the pinebook having a USB3 port, it works perfectly with gnuradio giving you two independent tx/rx chains at 60Mhz wide. I’ve used most SDR’s, it performs as good as USRP.
