[USRP-users] Setting send_frame_size for x300 sets recv_frame_size as well

Hello, When setting the send_frame_size or recv_frame_size in a usrp source for an x310, it sets them both the minimum of the two. Is this expected behavior? This seems to be behavior stemming from x300_impl::determine_max_frame_size in host/lib/x300/x300_impl.cpp where the receive and send size

[USRP-users] proposed patch for rfnoc_block_impl.cc

Hi, After some testing it turned out that when creating a rfnoc block that sends timestamps for packets, the output stream is not tagged. The patch below solves the issue and also removes the annoying timeout message that comes out whenever a block is not sending data so often. Hope this helps an

[USRP-users] problem installing uhd-fpga related to pyqt5

Hi, I am installing gnuradio/rfnoc on a Ubuntu 14.04 machine using Pybombs. Everything goes well until it starts to install uhd-fpga, and the first thing it tries to do here is install pyqt5 (PyQt 5.6). When configuring the pyqt5 package, it says "Configuration failed. Re-trying with higher v

Hi Snehasish, You should not be using a Throttle block when you have any actual hardware within the flowgraph. Note, in order to write 200 MS/s to disk, you'll most likely need a PCIe based SSD, or SSD Raid configuration. I've had success with an Intel 750 Series PCIe based SSD to write 200 MS
