These are neat little machines.  But this one is still sticking to it's abnormal inner oven
temp and is not moving.  I'll let it cook a little longer then may have to do some invasive
diagnostics.

I keep an odd assortment of whatever-I-can-find oscillators around the lab for use
as external time base clocks for frequency counters that I use to look at
frequency offsets in stabilized light sources by heterodyning their outputs against a
calibrated optical source to generate more easily measured RF products in the
microwave range.  I'm hoping this little guy will start to show its stuff soon.
