This is a demo of my Flex 6300 QSK capability using both shared and separate receive/transmit antenna. A remote QRP transmitter is sending repeated BK into a dummy load. I am keying the Flex with its internal keyer and my paddle at speeds from 25 to 100 WPM. Results with the shared antenna are better than most rigs however with separate antennas results exceed any rig I’ve tested. “Virtually full-duplex” is the best I can describe this. And for a bonus….No relay noise! Pin diodes do the job. 73 N4LQ
