Can anyone offer any advice or pointers for where to start? I have some programming experience if that's what's needed. The VITA-49 protocol isn't that complicated. I'd write a simple "interstitial" C program that reads the VITA-49 packed samples from your UDP/TCP port, and then sends them along a FIFO that Gnu Radio can open as a file source. > > Or even better, write a GNU Radio block that does that and submit it to > github! > > MB Yes, that would be fab. I would caution that because VITA-49 doesn't actually specify any encapsulation mechanisms for any higher-layer protocols, there's no "standard" way of placing VITA-49 over TCP and UDP, it is necessarily proprietary. It would be much better if there were a standard encapsulation--that would make having a Gnu Radio block be a very desirable thing...
