Unless the mute block causes an EOB tag to be sent downstream to the UHD
sink, that won't have the desired effect.

When doing half-duplex, sharing a common RF port, the USRP needs to know
when you've ended a "burst", so that it can
switch the antenna port between the RX and TX. And again when you
start transmitting, it'll need a SOB tag to cause
the TX state machine to wake-up.

The usual mode implemented by gr-uhd is continuous streaming on TX.
