Wide-Band Cross-type Radio Telescope DKR-1000 - is a meridian instrument consisting of two arms: East-West and North-South. Each arm represents a parabolic cylinder with the width of 40m and is 1km long. Wide-band feeds allowing to observe in the range from 2.5 up to 10 meter band are situated along the focal line of both arms. The DKR-1000 radio telescope provides unique possibilities for pulsar investigations, observations of spectral radio lines corresponding to transitions between levels with principal quantum numbers near 750(!), and studies of the radio sources flux density variations.
