Hi, I just use the new KVG O.70 design a small OCXO box and PCB, the test result show -109 dB/Hz (10Hz), -132 dB/Hz (100Hz), if more than 100Hz, the noise floor is low than my reference, I can not test/verify it, but I think official chart is correct (please check the attached PDF file).
I also have another KVG O-40, if you need the O.70, I can sell to you.
