Review. An alien civilization occupies a planet circling a brown dwarf, several light-years away.

The extraterrestrials have come to love broadcasts of MacGyver, on television channel 2, at carrier frequency 57.0 MHz. Their line of sight to us is in the plane of the Earths orbit. Find the difference between the highest and lowest frequencies they receive due to the Earths orbital motion around the Sun.
