It's easiest to create such a flow-graph using GRC initally, and then perhaps modify it if necessary to add your own logic, etc.
I've found it impossible to create a half-duplex transceiver with WBX and one antenna in grc. Would an open valve in the transmit chain stop the transmitter and enable the receiver, or would a closed valve in the receiver automatically stop the transmitter? I've experimented with several combinations, and all i found was as soon as the transmit chain is activated the receiver looses sensitivity. Is it possible with WBX and GRC alone?
