Any mode that depends on knowledge of bit timing can be made more efficient through external synchronization. This would include any of the PSK modes, for instance, or eventually a real-time version of WOLF. Even FFT-based tools like ARGO and JASON, amazing as they are in their present form, could be better optimized if the receiving computer knew exactly when each bit was due to start. Further optimization is possible if the frequencies were precisely known, too, of course--something which could be made much easier if the Navman 10kHz output turns out to be as good as Andy's first results indicate. 73 John
