As I understood the time travel to function:
Time ---->
S X earth at reception
p /
a / signal
c X------------------------X earth at transmission
e \
| \
V \ signal wave front
The signal recieved was electromagnetic radiation caused by the sudden
appearance of energy from the future at the reception point. This
radiation attenuated by normal inverse-square laws. Since the Earth
moved quite a bit relative to the frame of reference the signal traveled
in, beyond a certain time in the past the signal would be attenuated
too much to be detected. The computer was used to filter the encoded
information out of the background noise.
