The waves fall of with distance just as other undirected radiations
do. As a result they should be incredibly weak when we observe them
(if not, we have worse concerns!).
There are observatories working on detecting these with incredibly
sensitive equipment. Search for LIGO for an example.
Even assuming we all had H-masers at home (I wish... anyone know what
a VCH-1008 costs? is it too much to dream that it has a small price to
match its small size?), I'm not aware of any way we could usefully
measure gravitational waves, even ignoring their weakness, just due to
a lack of precise time transfer with enough time resolution.
