A narrow-band Free-Electron Maser (FEM) oscillator with a Bragg resonator was operated in the reversed guide field regime. A high-current accelerator generated the 300keV, 30A, 100ns electron beam. Radiation at 32GHz frequency and 500kW power, corresponding to ~5% efficiency, was measured. The measured FEM parameters agreed with predictions of a numerical simulation. The observed radiation frequencies compared well with ''cold'' microwave calibration of the cavity.
