SDR transceiver having independent mixer and ADC sampling clocks

2020-02-24 Thread Heikki Laamanen
Hi experts in SDR RF transceivers, I am working on a timing and synchronization system which generates a high-precision timing signal from a terrestrial broadcast signal. I am looking for a suitable SDR HW-board providing independent clocks for the RF mixers and the ADC. It seems that many

Hi all, We have some new AMD machines with RX 550 graphics. I want to run gr-fosphor on them. So far I've failed to make it work. It's an AMD system with RX 550 and Ubuntu 18.04 with amdgpu open source drivers. I work with GR 3.8-master (or 3.9.0.0-git) `4f53ac5a76e3ab05960a81905a570cd74d270

Hi Johannes, First off the RX550 should work just fine. I have a RX570 and run fosphor on it with no issues. I am using Ubuntu 19.10 though which is much newer kernel and newer Mesa. The OpenCL procedure looks fine and if it gets to that point, that also worked fine. For some reason the shader fa
