The LEA-6T has two modi. If i understood the documentation correctly
one is constant frequency w/o phase jerks and the other is aligned to
the 1PPS and thus has phase jerks.

The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
