Unless the mute block causes an EOB tag to be sent downstream to the UHD sink, that won't have the desired effect.One easy way is to use the mute block and have it controllable from a check box GUI element. Tom
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. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
