Several nearby flare stars have been observed with spectrometers on various large telescopes. The experience of several attempts to record stellar radio flares is summarized including an event on AD Leo that was detected by three widely separated large telescopes. The event is analogue to solar decimetric pulsations. An interpretation in terms of coherent cyclotron emission (maser) is given and the source size, exciter drift velocity and source magnetic field are estimated.
