It is all homebrew with an embedded processor and disciplined OXCO. I did not do any display shots (didn't think anyone would be interested) but it gave the "L" leap second warning yesterday and went 23:59:60 30 JUN 15 before ticking over to July 1. I built this over ten years ago and it has passed through a number of LS events no problem. Since the receiver uses a disciplined OXCO, it only decodes the time signal once per day to ensure time sync and check for warning bits (DST and LS). The rest of the time it ticks along according to the rules. It uses the LS warning bit to switch the time incrementing routine to a special LS version in the last minute of the last hour of the day. ___ 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.

Hi Scott, That's a nice WWVB result. Yes, the triple marker pulse looks is correct for a positive leap second. What did you use for a receiver?
