a) broadcasts aren't legal for US hams
b) ionospheric uncertainty in the skywave path makes this no better than WWV
c) Whats wrong with GPS and/or WWV and/or CHU or whatever?
d) A cheap Rb would give you a local reference that is much better than
what you could do with receiving something via skywave.
If you want something that isn't run by governments,and is a technical
challenge, how about pulsars? I'd guess (not having looked into it at
all) that is would be cheaper to set up a station to receive pulsars
than to run a Cs standard.
While I fully sympathize with the "stand alone" approach (that's one of
the appeals of HF comms in general.. you aren't depending on anyone
else's infrastructure), I don't know that setting up a time standards
station fits in with that..
