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. -- Paul Nicholson --
