Bill, It would be good if there is a way to easily put a tick box on the main page, maybe near the up/down arrows to shift up or down 60 cycles for transmit (same as SHIFT>F12 or 11). I used this several times in the contest.

I’ve searched the documentation. It explains that the column of numbers show the difference between the signal and the system’s time, but it doesn’t explain if the calculation is “signal – system” or “system – signal”. FWIW, my guess is that the value is “system – signal” and that the 200 or 300ms delta is due to signal processing delays in the radio. In my case, 2 to 300 ms processing delays could be considered about right, given the DSP filtering. Thanks. Dave / NX6D The DT figure is the measured difference between your PC clock and the sync of a decoded signal. A positive DT implies that the signal clock is behind yours. Positive components of the DT are the sender's clock being slow, and propagation delay. Also contributing are latencies including audio buffering and other processing delay which can be at either of both ends of the link and like propagation delay can only increase the DT, net clock difference can contribute a negative or a positive DT component. 73 Bill G4WJS. -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
