Microwave power generated by a virtual cathode oscillator is measured using independent diagnostics to levels exceeding 4 GW at 6.5 GHz. Variation of the cathode radius is shown to have little effect on the oscillation frequency, however, changing the anode--cathode gap is shown to have a strong effect on the frequency. Electron beam power to microwave power conversion efficiency is measured at 3.3%.
