Thanks to the folk here for pointing out the ublox receivers. I managed to
get one off eBay for ~US $30 with antenna on a board designed for hobbyists
with 3.3V serial and PPS outputs (I needed to add one wire for that) which
feed directly into a Raspberry Pi. It's still to be completed, but
most interested in you progress.
What will be the total power consumption of the pi and gps rcvr?

I've not measured the total, Paul, but the Raspberry Pi is about 700 mA and
the GPS receiver less than 100 mA, so
My perpetually drifting 10811 pretty quickly made it to the negative
voltage rail on the control voltage.
I was looking at the oscillator output with an O-scope and it looked
pretty nasty. My equipment is not so hot, so I first chalked that
up to bad probes. But I did some google work on that
oh thats my kind of basement wall wart. Place it on the wall and forget it.
I have nas drives that way. They spin down and power consumption is I want
to say 5-8 watts been a long time. May be lower. You access them they spin
up and get your data stay up for a while and back down.
A quite basement
Unfortunately, experience is a lantern lighting the way already done... and
it takes months to forge a good sword: no one should break any sword.

Is this an oscillator you just powered up after it had been off for a
long time? The most common versions of the 0811 are specified for
drift of less than 5 x 10e-10 per
Chris
HP 10811 can't drift that much that fast unless something is near broken, or
being connected wrong like gnds or PS voltage.
Check the operation of the oven. It must be close and sort of working
otherwise it would not be on freq as close as it is, but maybe it is
drifting.
