I tried a similar thing but got the same result as you did!
Would love to get some help. Anybody?

After much research, I learned this was done by tagging the first sample of a transmission with "tx_sob" and the last sample with "tx_eob" (there was also a "tx_time" tag, but I found the former option more convenient). I wrote a custom block that periodically tags segments out of continuous stream of data as a proof of concept; however, the transmission remains continuous as if there were no tag. I've checked with the tag debugging block to ensure my block acutally generates tags. My flow graph is simply: file source(repeat)->custom tagging block->psk mod->multiply const->uhd sink.
