Hi Paul, The Arcron Zeit was one of the early favorites for precise timing. There were a couple other WWVB receivers at the time but IIRC none were as interesting, inexpensive, or hacker friendly as the Arcron. Not sure what model you have (contact me off-list).
Here's a capture of a leap second by an Arcron Zeit.
