The Allen Telescope Array is now essentially complete at a first stage of 42 antennas. Although this is only about 12 percent of the final 350, its sensitivity for surveys is competitive, and we expect to build it out further. We summarize the overall characteristics and describe its novel features. It has four six hundred MHz bands that can be selected anywhere in the range 0.5 - 11.2 GHz. In one of the bands there is a 1024 channel correlator with a maximum bandwidth of 100MHz. It's outputs are the four Stoke's parameters. In each of two other bands, three simultaneous dual polarized beams can be formed in any directions within the primary beam. Another correlator is expected to be installed in the fourth band. Surveys are planned in both line and continuum. With the beam formers we expect to be searching for narrow band SETI signals and studying pulsars. SETI observations with the beam formers will be simultaneous with surveys made with the correlator. We show examples of recent observations, including both sources in large fields and interference signals found in the first SETI observations.
