Other Factors Influencing EME Communications
Doppler effect - 300 Hz at Moonrise/set
- At Moonrise, returned signals will be shifted approximately 300 Hz higher in frequency due to the Doppler effect between the Earth and Moon.
- As the Moon traverses the sky to a point due south the Doppler effect approaches nothing. As the Moon sets, signals are shifted lower in frequency until at Moonset they are shifted 300 Hz lower.
- Doppler effects cause many problems when tuning into and locking onto signals from the Moon.

Famous quotes containing the words factors and/or influencing:
“Girls tend to attribute their failures to factors such as lack of ability, while boys tend to attribute failure to specific factors, including teachers’ attitudes. Moreover, girls avoid situations in which failure is likely, whereas boys approach such situations as a challenge, indicating that failure differentially affects self-esteem.”
—Michael Lewis (late–20th-century)
“Do you believe that the dead can influence the living?... Could you conceive of a superhuman mentality influencing someone from the other side of death?... There is such a one.... Someone, something that reaches out from beyond the grave and fills me with horrible impulses.”
—Garrett Fort (1900–1945)
