I'm doing "closed circuit" transmit-receive tests with two SDRs, RF attenuators and Dream in both transmit and receive modes on different hardware. At transmitter end I'm using LimeSDR Mini and Dream in transmit mode with the following modulation parameters: interleaver=SI_LONG msc=CS_3_SM protlevel=1 robustness=RM_ROBUSTNESS_MODE_A sdc=CS_2_SM spectocc=SO_4 At receiver end I'm using RTL-SDR dongle outputting I/Q samples to Pulseaudio null sink and Dream with I/Q (pos) input. I found that the minimum...
