Very interesting effects. I doubt that there was actually any

three frequencies presented together in various proportions, going into
the test rig, due to the ground loops. For each signal being analyzed,

I think this done. Pretty sure that the True time doesn't work. Through the
serail port you can inquire for various information like time date
satellites and other details.
But it does not put out as an example a NEMA sentences. Thats has all the
details Lady Heather would need.
Thanks everyone.
