Abstract
The Experiment to Detect the Global EoR Signature (EDGES) is a radio spectrometer operating between 90 and 205 MHz using a single broadband dipole. The instrument recently completed a deep, three-month continuous measurement campaign in the Murchison Radio-astronomy Observatory (MRO) where it reached sufficient sensitivity to constrain the cosmological epoch of reionization (EoR). EDGES has also been used to conduct short, shallow RFI surveys in remote regions in the United States, including northern Maine and the Catlow Valley in southeast Oregon. Here, we show results on the RFI spectrum seen by EDGES at each of these locations and implications for upcoming low-frequency arrays such as MWA, LWA, LOFAR, and PAPER.
