Might the so called "frequency drift" associated with
SHGb02+14a actually be purposeful frequency modulation
of a repeating message similar to FM broadcasts of
earth radios? I know that normal modulation of a
carrier signal would probably be in a much more narrow
frequency band, but might not doppler effects on a
transmitter traveling at relativistic speeds produce a
similar broadening of the modulation range of such an
artificial signal? I do think it might be prudent to
determine what characteristics a fast moving FM
broadcast would have from 1000 ly away.

Also I am curious why SETI scientists think that
extraterrestrial civilazations would use the frequency
of absorption/emmision of hydrogen to attempt to
communicate with us. Wouldn't this make their signal
seem like a needle in a haystack rather than making it
conspicuous? Wouldn't it make more sense to use a
frequency that would stand out against natural radio
sources?
