[time-nuts] Re: Custom Wenzel OXCO with unusual output

The Wenzel in the picture you sent looks exactly like the one I have!

So what is this, and what is the function of the Ext Ref input, and the Status line?

As an aside, it draws 20 mA at startup and never varies from that, so I don't think it is a OXCO.

The other SMA is an external reference input. I have seen one of them on a Miteq satellite upconverter.
