only a test with DFCW-Opera ;-). Just another idea to generate an Opera signal with an uninterrupted carrier, as a workaround for transmitters with flipflops. The upper frequency carries the desired modulation, the lower one just dumps the carrier during the gaps. Choosing the FSK shift as a multiple of the symbol rate preserves the phase.
 
Due to poor energy efficiency, this is NOT the recommended technique to generate a coherent carrier;-)
