Bugger...we only have on X Mit crystal for this old beast....We'll try again another night.

If you run a DDS VFO with a voltage amplifier on the output to increase the drive you can connect it to the crystal socket with a bypass capacitor. This will allow you to go to any frequency. I have mine set to about 30 volts PEP  drive off the DDS. This works great on older vacuum tube transmitters or any crystal controled transmitter.
