[time-nuts] WWVB phase-modulation test

Just wondering if anyone on the list is monitoring their WWVB gear at the
moment?  I got in a bit late, but I have been recording my 8170 since about
0300 and it has remained locked.  QTH here is about 1500km north of Ft.
Collins.

psk fixer-uppers not working all that well. Back to the drawing boards as
they say.
But at least I can see whats up.
