Paul, everything I seen done in this frequency range has been a small coupling cap in the base/gate of the crystal oscillator - small enough that the reactance was large relative to the base/gate impedance. The resulting injected signal amplitude was ~5-10% of the normal operating amplitude at the base. Lock detection was done with a mixer looking for DC output. > Always on till a brief pulse from the 1 or 2 MHz ref cuts it off.
