Graham - I built the G3RUH GPSDO variant dead bug style and driving my QRPLabs Ultimate 2 transmitter kit/TS850/870 locks - works a treat and the OXCO keeps the room warm with a few Watts of heat :-)  

I need to finish the tripler for the R75 which I know I started a couple of years back but the board is hidden under a pile of debris somewhere...but in all honesty the cal/stab is pretty good enough at LF without it here.

First leaves are turning yellow

G3RUH's GPSDO uses the Jupiter's 10khz output to phase lock to a 10Mhz 
OCXO divided down to 10khz in order to discipline the oscillator.
