I am looking for a way to add the OCXO inside the receiver. There is a coax P2 on the daughter board for the 10 Mhz in plus J13 (5 +5 pin). I guess P13 is feeding + 5 V, +12 V and - 12 V. A VCO signal to control the OCXO should be there too.. Has anyone the same unit, at least to get a picture ? Unfortunately no drawings on the web. Cheers
