When I run dvbt2 transmitter examples from gr-dtv without any hardware, “Probe Rate” block in GRC shows 15e6 samples per second at the output of the Tx (which needs about 9 Msps to work in real-time.) Next, I connected USRP B200mini, but it showed underruns. Talking to the community, they said UHD is heavy and suggested other SDR modules like LimeSDR. But the problem still exists using LimeSDR-USB! I wonder if there is a way to make “LimeSDR Sink (TX)” catch up with other blocks. Details: HW: Orange Pi 5 plus (32GB) OS: Ubuntu 22.04 GR: v3.10.11.0
Thanks!
