[time-nuts] Cheap Rubidium

[WarrenS]

I Must not get it, Or I'm missing something.
Some seem to be going on and on about a little added DC heater current that can be held to about 10% of what the unit draws
Why does a little added DC heater current any more of a problem that what you do with the leads etc of the main power?
(And with a few simple tricks you can also reduce the effect of the changing heater current so it has insignificant effect) 
Have to work a bit harder to say the same about putting AC or RF into the heater

Sure, but having a sufficiently high frequency makes it relatively easy 
to clean up, as well as it should be reduced by normal loop filtering 
and oscillator integration.
