I agree. Very nice, but my lab bench is full of junk, more junk and 
essentially a lot of junk all over the place.

The remaining issue on that rubidium is if there is any plans to bring 
it into GPS control? Just logging the PPS against a PPS from a GPS 
regularly would suffice to get some aid in trimming the rubidium up.

Cheers,
Magnus
