Hi Marcus and Ellie, Thanks again for the flow graph Marcus. It's a very impressive piece of work. If one has only one SDR, it is necessary to change the input number of channels to 1, I think(?) Then connect the 2nd channel (chan1) to the output of the source block. The modified .grc file works right away.
