Building my own Rb vapor cell standard or H-maser is on my list of Things-I-have-to-do-before-I-die :-) If I had to do one of those now, I would go for a Rb vapor cell with dual-resonance using an external cavity laser diode for pumping. The electronics for such a thing are relatively easy, if you are not afraid of Jiga-Hurts and using these pesky QFN packages. But it isn't cheap either. There was a discussion started by Bert[1] where I ventured a rough calculation what I think it wold cost. Though I think I have understimated the cost of an ECLD (it's more like 1k-5k from what I have read) Attila Kinali [1] search for "thinking outside the box" in the archives -- It is upon moral qualities that a society is ultimately founded.
