There are several (natural) ways to get a short pulse (amplitude modulation) from a rapidly spinning source.

Had the frequency sweep modulation been linear, then I might suspect an other-than-natural source. But -- the freq sweep is nonlinear...

I just had a really cool thought, worthy (IMHO) of inclusion in a science-fiction story.

What if FRBs are caused by the lighting-off of a relativistic-drive spaceship somewhere far away? Perhaps with it's "exhaust" (or antenna, or plasma beam) aimed directly at us.

Kind of the galactic equivalent of the sound of a hot rod peeling out half a mile away.
