One straightforward approach to building an ENDOR spectrometer is to take a conventional EPR spectrometer, add the ability to produce a sufficiently high radio-frequency magnetic field in the microwave cavity, modulate this field, and then try to detect the change of the EPR signal, the ENDOR signal, with a lock-in amplifier. However, this will usually not work satisfactorily.
