Hi Hal,

My impression is that it's easier to manage all-sky coverage at x-ray with
a small spacecraft package (I think millisecond pulsars generally emit at
both microwave and x-ray). Also there's some interstellar scintillation at
microwave frequencies, which would hurt short-term timing performance
(something like the ionosphere's effect on terrestrial GNSS).
Cheers,
Peter
