Hi Ian, I had exactly the same problem with my XV 432 and scratched my head for some time. The outcome was that I had during construction switched the coils to be used for L4 and L19 (the two unshielded coils). This had the effect of not allowing me to set the LO on frequency. it would slide off either side of the wanted frequency and the crystal appeared damped and would stop oscillating. Once I swapped the inductors over and re-aligned it would sit on fequency perfectly once warmed up. I fully recomend the crystal oven and high accuracy crystal and leaving the oven on all the time using the jumpers.
