A long Josephson junction dc biased on a zero-field singularity and emitting radiation at microwave frequencies is irradiated with external microwave power. This power can be supplied either by a room-temperature oscillator or by another long junction. We find that the oscillations of the junction can coherently lock to the external signal for frequency intervals ranging from 500 kHz to 50 MHz. The dependence of the width of these intervals of coherence on the external microwave power is measured for the case in which the power is generated by a room-temperature oscillator.
