The wiki page on IRIG has the basics. I expect you are seeing a 1 KHz signal that's AM modulated at 1 bit per second. It might look cleaner if you sync your scope on the PPS signal. If you delay out far enough you can probably find some bits that are changing. -- These are my opinions, not necessarily my employer's.
