Do you have a Trademe auction number?
I am currently looking down the DIY lab frequency standard
rabbit hole and it is looking a lot deeper than $40.
It looks like many of the Aliexpress U-Blox Neo gps modules are
probably fake and gps based time has high phase noise.
The cheap fake gps modules would be just fine for running
slaves or comparing against a master.

I have been looking at using a GPS receiver to use as
reference time for a RF signal generator upgrade.
I have also been working on developing a arduino based
controller that will drive both a Solari Udine Cifra 12 and
Synchronome slave clocks from a Synchronome master.
It would not be difficult to add a GPS receiver to the
Arduino controller that would either replace the Master or
accurately measure the Master error.
My plan was to make just one controller for me but I
thought perhaps others might want one. Is that something
anyone else would like to own?
