Hello, I'm working on project in gnuradio, in which I'm trying to toggle on and off the transmission from the USRP.  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

You can also do precisely timed burst to stream conversion in pure-software which is a bit more portable For one example of how to do this using gr-eventstream tools see the transmitter in https://github.com/osh/gr-bitcoin -Tim On 02/08/2014 02:37 PM, Price, Nathan D. (ST-Student) wrote:
