Hi Maxim, UHD/RFNoC doesn't need any "special" capabilities of your network stack; only the ability to pass through relatively high-rate data without reordering packets. I had students myself that worked with N-series USRPs under WSL, that works just fine. The Radioconda installation method o

Hi, don't have a device to test with me, but don't forget that the *tuning* to that frequency might be technically possible due to FPGA frequency shifting, so that indeed the frequency 1 kHz gets shifted to baseband, 0 Hz. (You being able to observe the LO hints at that: the "physical" tu

Hi Ojas, it's a bit hard to know how that VPN of yours is actually set up. In general, doing arbitrary other networking on the same machine has absolutely no effect on UHD, as long as the packets to and from the USRP still go through regularly. What might be happening here is that the VPN est
