Hey, I'm losing my mind, apparently. Sorry about the confusion. I was
recently hacking on timed TX and my brain apparently read source as sink.
The easiest way to get around it is to schedule your receive thread to
start sometime less than 1 second before your set_start_time() call
expires. This w

("tx_eob") as well as a transmit time ("tx_time"). To issue a start of
burst, for instance, use:
add_item_tag(0, //stream ID
nitems_written(0)+i
Hello all,
I've been trying to use the set_start_time() method of usrp_source to
