A longer run measuring the phase of the NEO-7N frequency output,
compared with the Trimble.

There are a few spikes, such as this one

 http://abelian.org/vlf/tmp/170714b.gif

About 15 degrees offset if scaled up to 130kHz.

The NEO-7N antenna is on the window ledge so sees less than
half the sky.  Just before 120,000 seconds I moved the antenna
closer to the window and we seem to have fewer excursions since,
but the antenna is still only getting half the sky at most.

Now I'll move it outside to the shed where the antenna is not
so obstructed.
