Abstract

The RFI environment at the Nuffield Radio Astronomy Laboratories was examined extensively in the frequency band 1404 to 1444 MHz using the DSN Advanced Systems’ Radio Frequency Interference Surveillance System, An uncooled FET amplifier (62 K system temperature) was placed on the newly acquired 12.8-m antenna, and unlimited observing time was made available to the SETI project. One night of observing at 1667 MHz was made available on the 76-m antenna, Preliminary results of four investigations are reported here: (1) full scans of the horizon, cataloging RFI events between 1404 and 1444 MHz; (2) lunar reflections of terrestrial RFI signals between 1424 and 1444 MHz; (3) noise background (spectral baseline) distortions caused by galactic neutral hydrogen emission at 1420.4 MHz; (4) low sensitivity search for spectral features of F, G, and K Stars.
