New Long Wavelength Array being used for SETI They have built a new Long Wavelength radio telescope Array in New Mexico beside the VLA and it might be doing some SETI work! The Long Wavelength Array will use a radio frequency of 20 to 80 megahertz, says NASA, which corresponds to wavelengths of 49.2 feet to 12.5 feet.

Just a thought does seti check these long wavelenghts also? I just wondered if past work units are checked. |

This would correspond to terrestrial radio and television frequencies |

The Arecibo data we process here are from a band 2.5 MHz wide, centred on 1.420 GHz; accordingly the wavelengths range from about 21.09 to 21.13 cm. Hydrogen produces emissions in this part of the spectrum. |

Do false positive signals permiate signals received at Arecibo, a signal that has nonterrastial artificial nature but in fact might be caused by natural celestial events, such as x ray emmisions from a singularity, pulsars, |
