after much review of Tutorials and Examples and various experiments over the course of many days, i give up trying to do this on my own.
i do not understand why the best i can do with the flowgraph (attached) using the Constellation Modulator and a BPSK Constellation Object with a repeating input of "Test" (4 bytes, ASCII) is an output of "W7EF" (4 bytes, ASCII). where has this gone wrong? did i miss something? have i managed to make a simple thing difficult instead? thanks in advance.
