Re: [Discuss-gnuradio] UHD stream tagging

Someone correct me if i'm wrong, but the PSK mod won't propagate stream tags.

The burst tagging won't cause the USRP to stop transmitting -- it tells the USRP not to expect any more samples, but any delay logic must be implemented in your code.

I tried a similar thing but got the same result as you did!

Would love to get some help. Anybody?

My flow graph is simply: file source(repeat)->custom tagging block->psk mod->multiply const->uhd sink.
