Due to the timing reversal of the pulses from each station this results in solid carrier during the data bit times (no matter the bit combination: 00, 01, 10, 11) as the signals are added. The marker pulses every 10 seconds give a 0.6 sec gap when both stations are at reduced-carrier. And the double marker at the minute boundary gives a 1.6 sec gap with a 0.4 sec pulse in the middle. I thought this was sort of amusing. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
