Does anyone know if when unlocked it is possible to apply a tuning voltage to the Phase Lock Voltage monitor pin? What good is it to have an OCXO that needs to lock to a external frequency and is 4 kHz off when unlocked? When locked, it comes up on frequency from first power on, so why would an oven be needed at all? If interested, take a look at my qrz.com page for links as to why I am doing this. I have fallen down the rabbit hole of more accurate frequency!
