Microwave radiation from extensive air showers is expected to provide a new technique to observe UHECR. We developed a set of radio telescopes each of which consists of a 0.45 m parabola antenna in Ku band, a power detector and a waveform digitizer. Firstly, we had coincidentally operated the radio telescopes with an air shower array consists of nine plastic scintillators with about 10 m separation for several months. Secondly, we moved and installed the telescopes just beside the Black Rock Mesa fluorescence detector (FD) station of the Telescope Array experiment, and we operated the radio telescopes coincidentally with FD event trigger. We report the experimental setups and the results of these measurements.
