I think these clocks are tuned to one particular radio station, so by
taking
only one clock you automatically limit the region of the earth in which
you have accurate time available to a few thousand miles from the station.
Depending on your intended cruising area
this might be acceptable. On the other hand I think it is less elegant,
but that is a consideration of no practical importance.

BTW, I ran into http://www.cl.cam.ac.uk/~mgk25/lf-clocks.html, which might
be of use to you.
