That's great news.  My OCXO order seems to have stalled; I need to
ping the seller about those.  It sounds like people are fairly
confident that the PPS signals are working correctly (not wobbling)
anyway, but I have some other reasons I want to get a precise local
timebase going.

In other news, TI apparently has some new GPS chips.  Haven't
investigated, but would assume the cost of GPS is coming down even
farther soon:
