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.

What Freqs are we chasing? Hydrosphere on Earth size mass for long range detection? This is better than chasing submarines, ships, earthquakes, etc.

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,
