That's a great project, Richard. I've been following this with interest as I find this kind of thing fascinating.

The Jupiter GPS receiver is ex-military equipment and is the TU30-D400 version which uses 3.3V power but outputs directly to the 5V TTL on the Veroboard. The OCXO is another ex-military pull that has a pretty good specification, and the manufacturers in the USA still answer email enquiries about it!

That's pretty ingenious and it looks great, too. Thanks for sharing!
