Nope, you won't but nor would I, I tend to build things like that to get a job done and then chuck them in a box or tear them down.SMA connectors between boards and some shielding may improve matters but I wonder how good the 2MHz input looks on that spectrum analyser and if it shows the same pattern 'divided by 5'?If you want to explore and experiment more it's worth thinking about what you intend to achieve and how the different approaches work, all the various 'frequency standards' have advantages and disadvantages, some are great short term, some are pretty awful.FWIW, it's not that much more difficult to 'discipline' a cheap OCXO and get a really clean signal.It is however considerably more difficult to discipline it well
Is this a GPSDO? Afaik, those Ublox modules have a TCXO in them, where the 24MHz is not disciplined ( derived/compensated ) with the GPS signal.The 1 PPS signal is, and you need to use that with the usual controller to make it 10MHz.

I may as well throw it in the dog.
Justanothername,I just separated the pcbs, powering the multiplier with its own supply and things are looking as they were.
Best I can do, I'm afraid.
Very encouraging, Steve. I'll have to get busy.
Does it jump occasionally to keep it in line with the 1pps?
I like the fact that this is simple and cheap.
WRT battery...18650, or bigish li-po?
On board patch antenna, or sma in?
I love these design by committee projects.
