I'd like to find a Rb standard [1] one day...
[1] Yes, I realise that a Cs beam is a primary standard, but the tubes in
said units have a finite life by design (the Cx is being used up all the

lot longer. THus it's more practical for me.
Decent Rb modules can be had for well under $100 nowadays. You
should pick one up!
