What is the approximate maximum separation along the surface of the Earth between two stations communicating by moonbounce?

  1. 12,000 miles, as long as both can “see” the moon

E3A02

What characterizes libration fading of an earth-moon-earth signal?

  1. A fluttery irregular fading

E3A03

When scheduling EME contacts, which of these conditions will generally result in the least path loss?

  1. When the moon is at perigee

E3A04

What type of receiving system is desirable for EME communications?

  1. Equipment with very low noise figures
