Hi, We are amateurs and could provide another time distribution experiment especially during Field Day events. I mean setting up time beacon or beacons that send e.g. every 15 s a short pulse, say 100 ms, on the base carrier frequency e.g. 14.080 MHz. Timing of that pulse could be 'minute mark - 1 s' or something similar agreed time. It would allow manual PC time setting in the same manner as time marks of standard frequency stations. That transmission would not disturb any FT8 message as nobody should transmit at that time. It could be more useful, if the beacon frequency is set to 1 kHz up (14.081), then you could hear it without detuning VFO and disturbing you normal operation. Well, you could get same information from dT values providing there are enough time accuracy in other stations and you timing is good enough for decoding.
Of course those beacons should be carefully synchronized to an accurate time reference e.g. GPS. Depending on local regulations also a station identity shall be sent at regular intervals using some applicable modulation perhaps just before the time tick. I think that voluntary stations would provide this service as needed. You could automate the time setting with a suitable program, if that could be made safely and reliably (perhaps the pulses needs to be modulated for identification), but that's next step if ever considered useful. 73 Reino oh3ma _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
