The CSIRO 64 m radio telescope at Parkes, NSW, has been used to survey the region of the sky along the plane of our galaxy known as the Milky Way. The radio receiver, a broad band hybrid-junction radiometer operating at 2700 MHz employs twin receiving channels, each with two-stage synchronously pumped degenerate paramps with an overall effective bandwidth of 200 MHz. Installed on the 64 m telescope it gives a system noise temperature of 80 K and a half-power beamwidth of 8.2 min of arc. A series of contour maps covering the region from galactic longitude 61 deg, through the galactic enter and to the anticenter region at 190 deg, have been produced, and the positions and flux densities of over 800 radio sources are listed. Profile pictures of selected interesting radio sources have been drawn with the aid of a computer. Following the resurfacing of a section of the reflector, mapping of selected areas at 3.4 cm is in progress.
