Abstract
Fast Radios Bursts (FRBs) show large dispersion measures (DMs), suggesting an extragalactic location. We analyze the DMs of the 11 known FRBs in detail and identify steps as integer multiples of half the lowest DM found, 187.5cm−3 pc, so that DMs occur in groups centered at 375, 562, 750, 937, 1125cm−3 pc, with errors observed <5%. We estimate the likelhood of a coincidence as 5 : 10,000. We speculate that this could originate from a Galaxy population of FRBs, with Milky Way DM contribution as model deviations, and an underlying generator process that produces FRBs with DMs in discrete steps. However, we find that FRBs tend to arrive at close to the full integer second, like man-made perytons. If this holds, FRBs would also be man-made. This can be verified, or refuted, with new FRBs to be detected.

Conclusion
We have noted a potential discrete spacing in DM of FRBs. Identified steps are integer multiples of 187.5cm−3 pc, so that DMs occur in groups centered at 375, 562, 750, 937, 1125cm−3 pc, with errors <5%. If this holds, future FRBs would show DMs in these groups (and per- haps at the base 187.5cm−3 pc, or larger integer multiples beyond 1125cm−3 pc).
In case this would hold, an extragalactic origin would seem unlikely, as high (random) DMs would be added by intergalactic dust. A more likely option could be a galactic source producing quantized chirped signals, but this seems most surprising. If both of these options could be excluded, only an artificial source (human or non-human) must be considered, particularly since most bursts have been observed in only one location (Parkes radio tele- scope). A re-assessment of man-made phenomena, such as perytons (Burke-Spolaor et al. 2011), would then be required. Failing some observational bias, the sug- gestive correlation with terrestrial time standards seems to nearly clinch the case for human association of these peculiar phenomena.
In the end we only claim interesting features which further data will verify or refute.
