Electron cyclotron resonance plasma heating (ECRH) system has been recently installed on the gas dynamic trap (GDT) magnetic mirror. Two microwave beams are injected into the plasma at an angle of 36° with respect to the machine axis in a form of extraordinary (X) waves which are subsequently absorbed in the first harmonic cyclotron resonance. Each microwave beam is generated by a Buran-A type 450 kW/54.5 GHz gyrotron. The article reports on the first microwave injection experiments with limited total power of 300 kW. Adjustment of experimental conditions and magnetic field reconfiguration resulted in an increased diamagnetic signal, electron temperature and other plasma parameters
