Now Stefan is going to repeat a 3 character message each night, with exactly repeating timing and phase. This allows the signals to be added, to accumulate enough S/N for a decode of the message. Stacking - a bit like the technique astronomers use for images, except that this is coherent. We have to hope that the propagation at 17470 Hz allows the rxed phase to repeat well enough. Don't worry about the odd timing break, vtcat -p takes care of those quite nicely. Good luck, and if you see a high load average on your vlf02 PC, you know it's doing some useful work! -- Paul Nicholson -- |
