All comments are true. The accumulation of errors when entering the average value of dT is also true. But "auto dT" it must be for operator use. Then there will be no significant difference in dT in callLog.
25 июня 2019, 05:51:21, от "Sergio Yes UT9LI" < ut...@ukr.net >: Yes! Adjustment dT can be organized in the program itself. Discarding values, for example, dT greater than 0.7, calculate the average value of dT over all accepted values in the "callLog" list and automatically enter this value by analogy with the "+/- dT" button. In this case, the operator will generally forget about the synchronization parameter (except in the case of a start, when on Band call "NO!". 25 июня 2019, 05:33:43, от "Reino Talarmo" < reino.tala...@kolumbus.fi >: >Why actually set the computer clock?

Each time you station will set local offset based on dT and use it at transmissions. So you transmitted time will be slightly different than UTC time, not much but different. Other stations decoding you will use that time as a part of the mean or median calculation and will have another time difference to UTC. The result will be a random walk that may or more probably will result an accumulated time difference. That means at least an additional search is needed for current mean or median time difference each time you power on your computer and WSJTX. If there is only weak stations potentially decodeable on band and your computer time is off more than say 3 s, then it may take a long time before you can decode any signal. In addition each band over globe will drift to different dT mean values during no or bad propagation. The end result will be that local (within propagation) station will have a different timebase than DX stations and mean dT will mean that no DX will be decoded due to time difference. Of course your WSJT could then have different mean dT for different continents and that will be told in all spots… Nice chaos. 73, Reino oh3ma _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel -- Good Luck!
