Re: [time-nuts] Leap Second results: cheap GPS/1PPS receivers

It seems odd that the Garmin receiver got it wrong. The Garmin GPS-20 and -25, which I think are both older than the 18x, get it correct. The GPS-20 is so old it is a single-channel receiver, the GPS-25 is 12-channel but still 5 V power. GPS-20, June 1998:

Hi all; I have a Precision Standard Time Model 1020 that I have been playing with for the last few weeks, BTW I'm looking for a manual for it to scan or copy I will pay round trip shipping, so here's how it behaved at the leap second. This is a clock that strips the 100 hz time code to

Guys, We tested the recent firmware updates for the JLT products, and they correctly output the 23:59:60 time stamp, this firmware even outputs the correct leapsecond timing if GPS signals are totally lost and the GPSDO is in GPS-holdover mode during the actual event. We recorded a video of the
